I don't see the point in blocking arbitrary outgoing ports for an
application that is not going to make any connections other than relay
connections. The danger of Tor misbehaving on port 22 or port 53 is the
same as on any other port.

A port is a number. None of them is special. I really don't see any
reason to discriminate any.
