 The standard folder lists its contents in unspecified order. In 
 practice, it's in order of creation (I think.)

Creation date sequence seems to explain the order I'm seeing.

 
 You can get ordered folders, which support changing the order. In fact, 
 one ships with Zope in recent versions. Look for Folder (Ordered).
 
I've often wondered what 'Folder (Ordered)' was for. 

Is there an example of its usage I can take a look at anywhere?

Make one on your box and look at it. It's not like you can't just delete it.

What I did before ordered folders was to give each object a property 
(like 'sort_order') with an integer value designating it's place, and 
then sort the list on that property. Not terribly efficient, though 
using the catalog would help.

See the FileLibrary example, probably located at: 
http://localhost:8080/Examples/FileLibrary


It's not obvious how it does its multi-column sorting unless you study 
it quite a bit, though, so keep reading until it makes sense.  Go 
through the ZMI and look at the getFiles script (and others).



 I presume that under normal circumstances that sequence would be in 
alphabetical order of object ID.


That's not a presumption I'd make at all, but not unlikely.

Then you sort as appropriate.

Python's list objects have a sort method.

Zope has a module sequence with a versatile sort function, documented
in the embedded online help ;-)
