Jim, As you must have figured out by now, no one supports the precedence
and TOS fileds in any meaningful way. Those fileds were defined 15 years
ago because they knew they had to be reserved up front if anyone could
ever figure out how to use the information they purport to convey.
Now we finally see one soul (Dave Mills, the tireless experimenter) using
those fields to see if he can make some improvements in gateway behaviour.

The trouble is that everyone has to play the "game" if those parameters
are ever to have any use. The ISO equivalent protocols have also
defined those parameters and I see no use of them there, either.
