I think it probably just got jostled around and those are "boo boo's" (like a skinned knee) and it has scabbed up like your skin would. The oval brown spot in the last picture - can you pick that off (gently)? If not, it's just another scab.

I'd agree with Gardenfanatic, it looks more like mechanical damage.

Thank you both very much - it's reassuring to know it's fairly minor. Although, I'm not too sure how it sustained the damage, but I have been lifting it on and off the shelf a bit to inspect it...I thought I was quite careful, but will be even more so!

It could have happened in transit from the grower to the store where you bought it, or during handling by employees at the store. Might not have been anything that you did at all.
