For reference, under Mac OS X 10.6.6:
2 compare: nan = NSOrderedDescending
nan compare: 2 = NSOrderedAscending
nan compare: nan = NSOrderedSame
2 isEqual: nan = NO
nan isEqual: n = NO
nan isEqual: nan = YES
Just for fun, I tried it with [NSNumber numberWithDouble:INFINITY] instead of 2:
inf compare: nan = NSOrderedDescending
nan compare: inf = NSOrderedAscending
-inf compare: nan = NSOrderedAscending
nan compare: -inf = NSOrderedDescending
