Comment:

 I whipped up a cheesy little plugin to add the 'last_update_timestamp'
 column back in, albeit on the term_taxonomy table -- it used to exist on
 ye olde categories table. The field is updated when a post is published
 into that term (so this will work for any kind of term, which is a nice
 bonus).

 Once those are in place, show_last_update=1 works (because it now has a
 date to show!), as per line 1370 in wp-includes/classes.php.

 (My cheesy plugin also provides helper functions to return update-sorted
 terms because the core doesn't -- yet!)

 Not sure if this is super-appropriate for core, but at least describes how
 to fix the problem, and notes some more general benefits of resolving the
 bug in this manner (generic "last update timestamp of any term" support).

 Thanks. :-)
