Ben just pushed the change into our git master branch. You can retrieve the UUID in the following way:
ovs-vsctl get <table> <record> _uuid
It will be included in the next tagged release, but that's probably a few weeks out. Our git branch should be stable enough for testing purposes, but I wouldn't use it for production. If you want to use the existing release, you can use Ben's sed suggestion:
ovs-vsctl list port eth0 | sed -n 's/^_uuid *: \(.*\)$/\1/p'

If there are any inaccuracies, I think it's fine to hash them out on-list, since people can follow the thread. The dev at openvswitch.org mailing list is another option, since that's where a lot of designs are hashed out. It really doesn't matter too much, though.
