I name my tap devices (using ifname=...) as follows:

  tap.br0.05.1

where
  tap  -- this is a tap device
  br0  -- the name of the bridge
  05   -- the ID of the VM (each of my VM's has a unique numeric ID)
  1    -- The NIC # on the VM (1, 2, 3, or 4 depending on # of NIC's)

Then on my scripts I can extract the bridge name and use it.  This also has 
the advantage of helping me know just by the name what bridge this devices 
is hooked up to, what VM it belongs to, and which NIC it is inside the VM.
