Actually, I think "Owner" is always defined.

The problem is that symbols you define that otherwise have no meaning
to Condor are more like shell variables.  Try this:

OWNERBOOST = (Owner == "user1" || Owner == "user2")
RANK = 10 * ( 2 * $(OWNERBOOST) - 1 ) - LoadAvg + 20


The "$(<foo>)" syntax means to expand the variable "<foo>" in place.
