Is there a collation to sort the following strings in the following order 1,2,3,6,10,10A,10B,11?

I have a database with a VARCHAR column that contains integers of varying length. I want to sort them so 10 comes after 9, not 1, and 70A comes after 70. I was able do this with [PATINDEX()](http://msdn.microsoft.com/en-us/library/ms188395.aspx) , a CTE, and CASE statements in the WHERE clause. However, I was wondering if there was a collation where this would be unecessary.
