---------------
Another useful feature that isn't supplied by 'tal:repeat' is
sorting. If you want to sort a list you can either write
your own sorting script (which is quite easy in Python) or you
can use the 'sequence.sort' utility function. Here's an
example of how to sort a list of objects by title, and then by
modification date::
<table tal:define="objects here/objectValues;
sort_on python:(('title', 'nocase', 'asc'),
('bobobase_modification_time', 'cmp', 'desc'));
sorted_objects python:sequence.sort(objects, sort_on)">
<tr tal:repeat="item sorted_objects">
<td tal:content="item/title">title</td>
<td tal:content="item/bobobase_modification_time">
modification date</td>
</tr>
</table>

This example is copied from AppendixB Module sequence
http://www.zope.org/Documentation/Books/ZopeBook/current/AppendixB.stx
Note that in "sequence.sort(seq, sort)" the "sort" argument is a *sequence of tuples*.
While you save time copying, i waste time grokking.

Ditto the above comment. Please explain what the heck you're doing. I'm lost.

We're all lost. Get used to it. ;-)
