A bug:

  I expect line 103 (in "DocumentTemplate.sequence.SortEx") looks like:

                    if not basic_type(akey):

  Change this to    

                    if not basic_type(type(akey)):


Please file a bug report to "http://www.zope.org/Collectors/Zope".

Zope 2.7 contains the same bug.
