Using policy you may assign CoS values of 802.1p priority and ToS as you've demonstrated in your example. That traffic will be processed through the transmit queues of the switch according to the priority mapping. However, only ToS will be forwarded to the next hop on an untagged packet. Tagged egress is required for the 802.1p priority value to be included in a forwarded frame.

You'll want to make sure that CoS is enabled on the switch in order to write the ToS and priority values to your tagged packets egressing the switch. You can enable this in Netsight Policy Manager's General tab for the device or via command line on the switch with the "set cos state enable" command.
