If they're coming out of the Discman scratched, I think it's a mechanical scratching, not something done by the laser. Open the lid and spin the CD manually ... does it spin stably or does it wobble? What about if you jostle the Discman a bit?
The laser in a CD will start to wear down the data contained on the disc over time, but skipping shouldn't have anything to do with this, unless you leave the CD skipping in the Discman for a long time.
