The scratching is actually her trying to A. mask the smell of her feces and urine (so larger "predators" don't find her) and B. to put her scent into whatever she scratches on (scent gland in the paws/claws IIRC). Do you have other animals in the house that she might be trying to alert? Is she trying to tell others that the litter area is "hers?"
Try double stick tape on the areas like the walls. Cats hate sticky tape. It helps to keep cats from clawing things like sofas. Couldn't hurt to try. You should probably keep the deterrents to a minimum (in the areas the drive you the craziest). You could run the risk of deterring her from the litterbox completely.
I hope this helps. :)
ETA: And sometimes there isn't anything you can do. My vet once told me that cats can develop emotional issues and things such OCD. LOL I'm actually not kidding!
