Order By Slug – Not working when numerically prefixed slugs

Hi

I love this plugin but I’ve got one issue with is. I number my slugs so that I can show them in a certain order, such as 50-name, 75-name, 120-name, 125-name, etc, however once I get into the slugs prefixed with numbers that go above 100 for example then they get ordered before most of the double-digit prefixed slugs. For example, if ordering my posts by slug then the above posts would order as such:

120-name
125-name
50-name
75-name

I’m guessing that this is because it’s only ordering by the first two digits and doesn’t take into account any following digits. Is there a way around this or how to fix?

Thanks
