Break tryrule into two rules; one that prints the message, and another
that retracts the fact. Give this second one a negative salience
value.
(defrule tryrule1a
?a1 <- (alert (name ?name1) (globfacts $? ?gf1 $?))
(test (> ?gf1 10))
=>
(printout t "Got num: " ?gf1 crlf)
)
(defrule tryrule1b
(declare (salience -10))
?a1 <- (alert (name ?name1) (globfacts $? ?gf1 $?))
(test (> ?gf1 10))
=>
(retract ?a1)
)
You'll get the behavior you want.

You can use the multislot functions (nth$, in particular) to dissect
the multislot on the rule's RHS.
