You can put ports on tagged VLANs by setting their "tag" values:
ovs-vsctl set Port <myport> tag=1234
You can also add a "internal interface" on a tagged VLAN, if you want to be able
to, say, configure an IP address on that tagged VLAN:
ovs-vsctl add Port br0 vlan100 tag=100 -- set Interface
This is described in the Configuration Cookbook section of the

I don't understand why you'd want to use tag=0.
Make sure that your gateway understands packets with tagged VLANs.
