Usually loopback is not filtered[1].  You could try adding this ahead of
the above two rules:

  set skip on lo0

If Tor is listening on an external interface, then you should just need
to open that particular port

  pass in quick on $ext_if inet proto tcp to ( $ext_if ) port 8118

Otherwise, try logging blocked packets and see how it is trying to connect.
