I normally treat the divert as first in the chain (as a single rule)
ipfw add 100 divert 8000 all from any to any not layer2
I am not sure how even FreeBSD 10 will work with having two divert
rules. It should be a short circuit to detection, if all is well,
packet is evaluated by the rest of the rules.
