Jim,
show us the complete code of the rule and the fact
this new rule may work because ?rvu is smaller than 1, so (or TRUE FALSE)
gives true.
or with one item works as true value of that item. In your old rule fact
had 4.19, and pattern in or had 4.17 which IS different.

Then why does this work?
(test(and(= ?servicecode 847312380)(> ?quantity 3)))
(test(or(= ?amount 1.54)(< ?rvu 1)))
An or with two items works, but not with just one.
