Sort by multiple options in custom field

I think that if you make your choices list a value=>label list, this should work: https://wordpress.stackexchange.com/a/11454/20807

Instead of your current list,

1 : Ultimate Plus
2 : Ultimate
3 : Professional
4 : Commercial
5 : Business
6 : Free

It can also be in the order that you currently have

6 : Free
5 : Business
4 : Commercial
3 : Professional
2 : Ultimate
1 : Ultimate Plus

Then, the meta_key / orderby combo should get you where you want.
