Actually it is quite normal. BitTornado can use almost any outgoing ip port -- it will just only accept INCOMING connections automatically only on the narrow range of ip ports that you allow.
Notice that these ip connections I cut out of your list ALL connect to an ip on port 6881. Your computer is connecting to them on the ip port they use for incoming BitTorrent traffic.

Also notice that these connections:

tcp 0 0 192.168.0.3:6881 71.121.141.97:2211 ESTABLISHED
...are connecting to your ip port 6881 but they're not using ip port 6881-6899. That's because the outgoing port BitTornado (or even web browsers for that matter) use is random and/or decided by your operating system.
