curl -X POST -d '{"priority":"3",
"match": {"nw_dst": "10.0.0.1", "nw_proto": "UDP",
"tp_dst": "5002"},
"actions":{"queue": "0"}}'
http://localhost:8080/qos/rules/0000000000000001
"priority" of this command means that matching precedence of the flow entry.
(Please check "7.3.4.1 Modify Flow Entry Message" of OFSpec 1.3.4.)
Therefore, there is no related to priority of QoS.

If you want to treat CL2 as a high priority than CL1,
For example, Why do not try to set as follows?
Change before (current))
port 5001 (CL1) -> Set to Queue 0 (max_rate: 0.85M bits / sec)
port 5002 (CL2) -> Set to Queue 0 (max_rate: 0.85M bits / sec)
After the change)
port 5001 (CL1) -> Set to Queue 0 (max_rate: 0.2M bits / sec)
port 5002 (CL2) -> Set to Queue 1 (min_rate: 0.85M bits / sec)
The result should be as follows:
* The traffic sent to the port 5001 is shaped with up to 200Kbps.
* The traffic sent to the port 5002 is guaranteed 850Kbps bandwidth.
