You could put a screen door torsion bar on it but it should most likely be replaced since it is out of square.
If not familar with one, it mounts across two corners of the screen door then you twist the nut to pull or push the door to square. If rubbing on top you would want to fasten one end to that corner and the other by the jamb then toque as needed to pull down the upper corner of the door. They run about 8-12 bucks but come if a few sizes so measure first.
