I agree here. It's a bit arbitrary but would fit the "natural". But I
wouldn't insist on it since the setting is only about numbers.

Yes, it's a simple rule, and from this point of view I could very well
live with it. But it puts "04" before "3" which wasn't the intention of
the natsort in the beginning (if I understand correctly). For example,
Nautilus puts "03" before "4".
