when doing qos on bunde interfaces, the policies are applied to the member
links. so if you want to rate limit a bundle you have to do some
basic math or use a percentage as jared suggested.

http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-2/qos/configuration/guide/b_qos_cg421asr/b_qos_cg421asr_chapter_01000.html#ID105

When a QoS policy is applied on a bundle (ingress or egress directions), the policy is applied at each member interface. Any queues and policers in the policy map (ingress or egress directions) will be replicated on each bundle member.
