I have something similar to your idea already. The python script
supplies page number to a stored procedure which handles the actual
paging. The script takes the result from the proc and builds an html
table and handles column sorting on the table. The output of the script
is just a single variable so I can just use &dtml-var instead of the
Problem I have now is this new search interface makes use of full-text
searching on SQL Server 2K. The paging proc wasn't written to handle it
and will need to be rewritten from scratch. This will take a lot of time
and testing. I thought I could slap something simple and fast together
to use in the interim to allow people to start testing the search
I really do wish Zope would either fix or eliminate broken features. At
the very least have the curtesy to say "hey y'all, this is broke, don't
bother" so folks don't waste time with it.

In similar situations I have done the following:
1) call a python script/external method which: (i) does the db search;
formats the results as required for display; (iii) returns a tuple that
contains: list of search results, url parameters for 'previous' link;
parameters for 'next' link; url parameters for 'first link'; url
for 'last' link
2) use a dtml method to call the script/ext.method like
<dtml-let rStat="mySearchRoutine(parm1, parm1, ...)">
display code here eg. <dtml-var sequence-item><br>
or could be an html/css table, etc.
<a href="...?<dtml-var "rStat">">previous</a>
<a href="...?<dtml-var "rStat">">next</a>
<a href="...?<dtml-var "rStat">">first</a>
<a href="...?<dtml-var "rStat">">last</a>
This greatly simplifies the dtml and facilitates debugging and future
