Thanks Peter,
And If I wanted to anchor the number to the end?

%% matches at the end, as much as possible.

You could also do

num=${0##*[!0-9]}

(remoes everything up to the rightmost non-digit).

That even happesns to  be POSIX.

Also, why are you using ls?

Why not simply

gvim -p *(.om[1,$num])
