The default Transport Agent priorities on Hub server with anti-spam agents and ForeFront security for Exchange installed look like this:

If you need to change the priority of transport agents in Exchange 2007 you can use following syntax in Exchange Management Shell:

Set-TransportAgent -Identity AgentIdentity -priority Y

So basically if you need SCL stamped on the message before Transport Rule processes message, you can put Content Filter Agent on top of the filters by typing:

Set-TransportAgent -Identity "Content Filter Agent" -priority 1
