"My guess is that it was the CORE8 that was misplaced, ..."

Quite possibly - it's all guesswork. :-)

"I suppose you meant to write <=> on the right side?"

No, cmp was intended. I was aiming to indicate that cmp would give "11 115 12 130"; whereas <=> would give "11 12 115 130".

It would appear I failed to communicate my intent. Thanks for pointing this out and giving me the opportunity to provide clarification.
