the use case would be OSP using enum as backend.  in that case, OSP server
would need to map NAPTR preferences to OSP peer ordering where some
peers could be of same order.

enum doesn't discover any routes. it just returns an ordered set of sip
or tel uris.  once got those, OSP server could check if domains of any
sip uris are in its peer database and if so, it would include the tokens
of those in its answer.  OSP server would thus not need to look at the
user parts of the uris at all.
