Whoops.
You're totally right. I'm wrong and sorry.
Still, this only allows the sort attribute to be variable.

The new "sequence" module has got it all:

<dtml-in expr="_.sequence.sort(objectValues(),
                               (('title', 'nocase'),
                                ('bobobase_modification_time',
                                 'cmp', 'desc')
                               ))">
<dtml-var title><dtml-var bobobase_modification_time> <br />
</dtml-in>
