Hmmm, perhaps we could put the desired ordering in parens 
or brackets after the item to be ordered?

    (:pagelist order=$Group(PmWiki,Cookbook,PITS,*) :)
    (:pagelist order=$:Category(Bug,Feature,Documentation,*) :)

But then if someone wants to select only Bug/Feature/Documentation
(and display in that order), we get the unwieldy

    (:pagelist order=$:Category(Bug,Feature,Documentation) 
      $:Category=Bug,Feature,Documentation :)

So, perhaps it's more appropriate as some sort of marker that
means "order by" in the selection attribute itself, as in:

    (:pagelist $:Category=(Bug,Feature,Documentation) :)

which means to select only those pages where $:Category is
"Bug", "Feature", or "Documentation", and to display them in
that sequence.  To sort by name within those groupings,
one would use:

    (:pagelist order=$:Category,name $:Category=(Bug,Feature,Documentation) :)
