Actually the scars aren't 100% lined up. one is slightly off in comparison to the other. I honestly think she got the scar form the armor and the scar shown before/during the battle was an animation error. Since the main render for Weiss has the scar, it wouldn't be that bif of a stretch to assume it was an error.
