Thanks for clarifying. So if I use the current beta version,

 Yes :)
 

I tried and failed. :-(
I downloaded the zip-file
http://orgmode.org/cgit.cgi/org-mode.git/snapshot/release_8.0-beta.zip, copied
all the contents of the file into my paths (where org-mode 7.9.4 was working
happily before),
launched Emacs, byte-compiled the whole path

When I execute the agenda-command, I get the error message:
org-agenda-skip: Wrong type argument: stringp, nil
Is there any documentation about changes that might break something? 

Kind regards

I never needed that up to now (and first had to install make,

Another problem: org-export is missing, 
the file does not exist in lisp or
contrib/lisp.
I could not find anything about that in the mailing list, 
maybe I've overlooked it?

When trying to open an agenda, I get the error:

Did I do something wrong or is the typical beta-experience?
So then I think I've go back to 7.9.4 and await version 8 with patience.
(Or is there a way to get the new sorting features already with Version 7.9?

Concerning the instructions:
from my point of view it is not clear what has to be done to use the beta
version and what risks there are.
(For a programmer this might be clear, for a normal user this is not clear 
IMHO.)

Recently i did run into the same issue. 
Reordering things in my .emacs did the trick -
first set the load-path, especially the path where org-mode lives, then
the rest. And be sure, org-mode is loaded not from an directory with an
old version or from an build-in version. 
I thought, the configuration was so, but AFAIR there was an old path, which
was ignored by versions less recent. It was a mixed configuration in
office, so yet i can not look for this.

The thing I couldn't get to work was automatically starting column view
in my block agenda.  I can still manually do that with C-c C-x C-c

 I tried your code - it does what it promises.. however, you're right,
 it's not
 yet what I need:
 I'd need Priority A and B in one view (table),
 then sorted
 * Prio A first
 * Prio B second
 lines sorted by date descending (newest first) .. would that be possible?

I think that should be possible.


 If I understand the problem right, I can get the deadline/scheduled 
 information
 in the agenda only with the agenda commmand, not with tags-todo or anything
 else? This is a pity.

In column view you can see the data in any agenda view.  Dates are
normally only displayed in the agenda view which includes the
time grid.  This would only show past due and past scheduled items and
deadlines within deadline warning period.

 So theoretically, I'd have to use this agenda command and then tweak the 
 sorting
 function to arrange items by Prio first and then by date?
 (That's what I tried already, based on your setup, but I was not able to make 
 it
 work yet..)


Is column view in the agenda acceptable? I don't know of another way to
display the deadline and schedule information you want.

I can take another look at this over the weekend id you like.

Hi Martin,

From 

,[ C-h v org-agenda-sorting-strategy ]
| time-upPut entries with time-of-day indications first, early first
| time-down  Put entries with time-of-day indications first, late first
`

time-up should sort items with a date stamp and time with earlier times
first followed by later times.  time-down is the opposite.  I don't
think this has anything to do with durations.  Yes it only seems to
affect entries with a time component.  On today's daily agenda if I set
org-agenda-sorting-strategy to only be time-up then the grid is at the
to of the agenda followed by all of the other entries.  Any entries with
a time are interspersed in the grid.

With time-down the grid is in reverse at the bottom of the agenda.


 I tried to modify your Block Agenda by inserting the following block:

 (tags-todo PRIORITY=\A\ (
   (org-agenda-overriding-header Critical)
   (org-agenda-entry-types '(:deadline))
   (org-agenda-sorting-strategy (quote (time-up category-keep)))

This starts the agenda in column mode and shows category, task,
deadline, scheduled dates.

'q' exits column mode.

In the block agenda if you turn on column mode with C-c C-x C-c you get
the same information for all tasks in the agenda

It's probably not exactly what you were looking for...
