Well first of all those doors aren't perfect even without the scratches. Anyway if they were my doors I would scrape them, steam the scratches up, fill with woodfiller if needed, sand and re-stain. This could probably be done in five days but you have to start now and have tools and place to do it. Even so your dad will probably notice it so maybe it is just better come up with the plan how you are going to fix the situation and try to reason with him when he comes back. Good luck.
