I think the last line should read:

print 'ties=%s  player 1=%s  player 2=%s\n' % tuple(score)

Isn't it?
Moreover, if you would agree the following to be even
more minimalstic, you could replace line #5 by:

  outcome = (play[1]-play[0]) % 3

If you now wonder, why this yields the same output,
you may feel that there's something slightly uncomfortable
with "minimalistic" solutions like this.
