I guess this should not happen (it should be allowed to bind on lower
ports). How do you start your tor?

Anyway, to avoid permission misconfigurations IMO it's better to use
local higher port, redirect egress 80 port to 9030 with your firewall
while advertising on 80.

A torrc excerpt:
DirPort 80 NoListen
DirPort 9030 NoAdvertise

For PF on FreeBSD:
rdr pass on $ext_if inet proto tcp to $ext_if port 80 -> 127.0.0.1 port 9030
