OVS implements these features as described in the OpenFlow
specification, which says:

    A bucket is considered live if either watch_port is not OFPP_ANY and
    the port watched is live, or if watch_group is not OFPG_ANY and the
    group watched is live.

OVS does implement weights and I believe it implements them correctly.
What problem have you found?
