[c-nsp] QoS VLAN trunk Port

For Qos this works very well. I have an aditionall requirement.
Now I have to change the Cos values on the trunk Port. 

So there is trunk between an Cisco Catalyst 4500 and a Juniper ERX.
I want to change the CoS Values for every Vlan in a different way.

For Example: VLAN 15 CoS =5
             VLAN 10 CoS =3
             VLAN 20 CoS =1

My idea was to enhance the current policy-map configuration with
the command "set cos x", but unfortunately the switch doesn't accept
this
command, although it is documented in CCO. I checked the Feature
Navigator and
IOS 12.2(40)SG IPBASE has the feature "Class Based Ethernet CoS Matching
& Marking (802.1p & ISL CoS)".

So any ideas, why I can not configure this on my cat4500 ?
Is there another way to achieve this ?

Regards,
 Ahmad
