A simpler approach is to just evaluate the enum and return comparison value:

 var result = list.OrderBy(item => item.myEnum == myEnum.foo ? 1 : 2)
                  .ThenBy(item => item.myEnum == myEnum.boo ? 1 : 2)
                  .ThenBy(item => item.myEnum == myEnum.goo ? 1 : 2);

This way you won't need extra variables and a more readable code.

I found this reasonably simple as well:

var result = list.OrderBy(item => item.myEnum == myEnum.foo)
              .ThenBy(item => item.myEnum == myEnum.boo)
              .ThenBy(item => item.myEnum == myEnum.goo);
