Try to replace it with this:

static NSComparisonResult compare(id elem1, id elem2, void* context)
{
 NSComparisonResult (*imp)(id, SEL, id);

 imp = (NSComparisonResult (*)(id, SEL, id))
   [elem1 methodForSelector: context];

 return (*imp)(elem1, context, elem2);
}

I'm not sure what the hit in overall performance is or wheter that is in 
issue. Richard?
