I've had my fair share of scratches. Most tend to be practically invisible or easily camoflaged. In this print the scratch down her forehead and along the bridge of her nose drove me to distraction.
The processes described sound like what I do. To minimize scratches, I try to slow down and relax. I also wear gloves and do not leave the film unattended from beginning to end. But all it takes is one false move; bring one sheet up and touch the corner of the stack on the way up, and that sheet will be scratched in the important part of the image.
So long as you don't do that, you'll be fine.
Many have said that developing emulsion down minimizes this risk. I think mechanically they are correct.
