As long as you're aware of this "feature"...

Btw, shouldn't it be possible to do the sorting in a three-step manner as
follows? First split up the search result (array of page names?) according
to the group name (case sensitively), resulting in an array of arrays.  
Then sort the first array (of group name) according to the current locale.  
Finally, for each group, sort the page names according to the current
