this could be done using @unexec at the beginning of the pkg-plist file
such as :

@unexec [ -e /var/run/orion.pid ] && { echo killing orion.; kill `cat /var/run/orion.pid`; rm -f /var/run/orion.pid; }

an alternative would be to use killall such as :

@unexec echo killing orion.; killall orion; rm -f /var/run/orion.pid

FYI, the pkg-plist file is parsed and executed sequencially.
