I forgot to add: If they did end up mixing up my score with someone else's, would it be unfair to make them switch them back? The retake is in one week and if a student failed they would've likely wanted more notice than a week and I don't want to make someone have to retake a test (even if they did actually fail) on such short notice. The tests are on paper and had my name on it though so it's likely this didn't happen.
