Thanks for the pointer.  In the case in hand passing the dictionary:
   [[NSUserDefault standardUserDefaults] dictionaryRepresentation]
as suggested seems to do what I need.  The implication of the posting
you mention is that in fact no matter what dictionary I pass as the
locale, if something it will sort on the user's default locale.  I'll
continue to pass the standard user defaults dictionary none the less so
that my code still works if Apple ever properly implement the feature.
