Use array reversal instead of array sorting.

Browse source 
There's no need to do a full numerical sort here, since we know the
keys will be in reverse numerical order, because (R) searches in last-
to-first order. Not a big deal, but this is just simpler and
presumably more efficient.

Also cleaned up a rather confusing comment about (on) being used to
remove duplicates, which it definitely doesn't.
