Comment(by lschiere):

 Sorting happens at the GTK level though, not in the backend buddy list at
 all.  So sorting based on PurpleBlistNodes wouldn't actually change your
 display.  Sorting in the backend would result in a non-trivial performance
 hit, as it'd involve more disk IO, plus refreshing the screen to match the
 new backend, for every sort change.
