Not true, you "just" have to apply the policy route ("ip policy route-map
blabla") on both the physical AND the tunnel interface.

It works for me in 12.2(12a) at least. I can see, that I have set the
physical interface to process switching. I can't remember if it was required
for this to work.

Trying to understand the correct order of packet processing in a Cisco
router is .., challenging at least ..
