It doesn't really matter. It's just the order for which the dice is rolled for each player. Example:
Battle order:
Player A
Player C
Player B
The QM roles the die for Player A first, therefore when Player C comes up, The damage left from Player A's attack is still there. And he let Tesni and Hoke go first because they were much stronger then him.
EDIT: Doc beat me to it again! What is this, the third time?
