Just to add my thoughts here...Yes, I would see scratching to be a form of SI- from what I have learned from other ppl here. I had a similar question too, which I think I posted about (I can't remember now!!)- I started picking my lips- pulling the skin off them- when I was about 6 or 7 and never even imagined it as a form of SI until a couple of months ago. But it is a huge probelm for me, and my lips are in such a bad way now that if I try to smile to widely at the mo the bottom one is so raw it starts bleeding. So I guess that, as lex said, anything that brings emotional relief is SI...
