Jwfitt, The ATTACKS part of the character sheet for Dungeon World should be renamed to Damage. For your normal attacks you will mostly use Hack & Slash under Core Moves. But to answer your question, no, the /pbta rolls will not work in that field.
Also, on the character sheets I miscalculated the HP. It should be the Constitution score + your class starting HP. So for the Barbarian with a constitution of 15 his starting HP would be 23. I'll update that in the character sheet once I make a few other changes.
