I currently accept both equally since postal_code had been around a
long time before the Karlsruhe Schema. However, I would be happy for a
tag convergence on addr:postcode since it makes things a little
easier.

These days I only add addr:postcode and this is what I recommend on
the tagging page of the postcode finder. I wouldn't be averse to a
mass 're-tagging'. If people want to discuss this though I suggest we
start a new thread.
