Well, I'm not 100% sure I have this right but; if you are trusting
traffic on ingress then doesn't EXP get copied into internal DSCP,
which in turn is then copied into egress values based on mapping. So
you might like to:

mls qos map exp-dscp 0 8 16 24 32 46 48 56

...and then match cos for the priority queue on the LAN module.
