Hi Ryan,
I am pretty new to Jess, but I will take a stab at answering your
question anyway. ;-) Priority (or salience) attaches to rules, not to
the facts upon which the rules operate. If at a given point multiple
rules are activated, then salience can be used as a way to resolve the
conflict between them: the rule with higher salience gets to fire. But as
it notes in the user manual, doing this kind of thing is not considered
good style, as it is a step away from declarative to procedural
programming, and you start to lose some of the benefits associated with
declarative programming. (Of course, you gain benefits associated with
procedural programming.)
