As of this writing, "split" barcodes have worked well at two Nationals and several sanctioned matches.

 

It takes the onus off of the shooter of having to be sure he gets the right stage label on the score sheet each time.

 

It requires scanning two labels when you enter scores, but after 5 minutes' practice that becomes a natural movement.

 

I highly recommend that you try this system.
