If you are dealing with more than 2 ports, this might get complicated.
But in case of just 2 ports, you could check the ReceivedPort and set a
bflag during handling of the REGISTER request:

if($Rp == 5060) {
  setbflag(BFLAG_RECEIVED_ON_PORT_5060);
}

The bflags are saved with the registration, so you can check them in a
branch_route called after lookup and force the port to be used to relay the
request:

if (lookup("location")) {
  t_on_branch("USER_BRANCH");
  if (!t_relay()) {
    sl_reply_error();
    exit;
  }
}

branch_route [USER_BRANCH] {
  if (isbflagset(BFLAG_RECEIVED_ON_PORT_5060)) {
    force_send_socket(MY_IP_ADDRESS:5060);
   } else {
    force_send_socket(MY_IP_ADDRESS:5061);
  }
}

(obs: I actually, never tested this. I'm writing from my recollections of
similar problems I had to deal with).
