IMHO an MTA should not depend on Mail-headers for such things, BUT it
isn't impossible (at least i think so).
You could try to write some fancy redirect routers and rewrite the
addresses in a special way like $local_part@$domain.highpriority and use
a special retry rule for *.highpriority but thats just an idea ;). This
would need one router BEFORE your dnslookup router to strip .highpriority
and one after the dnslookup router to add it again.
