Chosen answer: There's no reason given and it is not part of the story line. Most likely, at some point during the filming of this scene, Emma Watson suffered some minor injury and needed to wear a bandage.
Answer: She could have injured it while she was on the Whomping Willow.
Answer: You can see blood on Hermione's hand when Ron says "Scabbers has been in my family for..." before Sirius says "12 years"
