You can't compare pairs for greater-than or lesser-than in REBOL. The
resons why were discussed exaustively on the list recently. If
you're looking for a long read, search for "pair" in the escribe
archive here...
http://www.escribe.com/internet/rebol/
and choose the "Tuples - Was Pair! thread" and "Pair comparison (was:
native? :==)" threads.

That's expected behaviour, and useful too. Gregg Irwin's written a
good article on pairs here...
http://www.rebolforces.com/articles/pairs1.html
which explains it a lot better than I could. Well worth a read.
