You could use a function call or defglobal to return the salience,
then use (set-salience-evaluation) to tell Jess to reevaluate salience
every time a rule is fired;
(defrule number1
(salience (get-salience number1))
...
(deffunction get-salience (?name)
(bind ?s (fetch (str-cat ?name "-salience")))
(if (eq ?s nil) then
(return 0)
else
(return ?s)))
(deffunction set-salience (?name, ?value)
(store (str-cat ?name "-salience") ?value))
(set-salience-evaluation every-cycle)

You'd have to store the values yourself in some kind of persistent
store -- a database, etc -- and restore them when the program starts
up.
