It seems a bug of rest_qos.py.
rest_qos.py stores Queues list of only last one.
(rest_qos.py clears all stores Queues list for every POST request...)
But Queues on OVS seems to be configured as expected, and can be seen on
ovs-vsctl command.
e.g.)
mininet> sh ovs-vsctl list Queue
_uuid : 1724da04-278c-4cba-ba6c-cd00e4f23f67
dscp : []
external_ids : {}
other_config : {max-rate="500000"}
_uuid : 775211a9-51ec-434f-92e7-38b9aa58864b
dscp : []
external_ids : {}
other_config : {max-rate="600000"}
_uuid : 1a5a5639-29df-4644-9c4e-ce1fcccb8665
dscp : []
external_ids : {}
other_config : {min-rate="900000"}
_uuid : cb67c45a-1776-4ceb-93b4-75f81a0ea248
dscp : []
external_ids : {}
other_config : {min-rate="800000"}

mininet> sh ovs-vsctl list QoS
_uuid : fe6220aa-c44d-4b0b-8f52-2b3228c480c8
external_ids : {}
other_config : {max-rate="1000000"}
queues : {0=1724da04-278c-4cba-ba6c-cd00e4f23f67,
