Thanks, Heather. It's beginning to sound like a consensus.
On reflection, the person who was surveying the identifying marks would be recording everything on the face first, before moving onto other parts of the body. So it would make sense to be noting scars on the nose and eyebrows, before arms and hands. It's completely consistent.
I've been looking at this for months and wondering about it, I'm so glad I asked. Thanks for your help!
