Mysql order number / character combined

问题

I have a SQL table with in a product-name field with the following values:

10b
 9b
 8b
 7b
 6b
 5b
 4b
 3b
 2b
 1b

These needs to be ordered from 1 to 10, but for some reason when i select with the following order: ORDER BY title ASC, then i get:

10b
1b
2b
3b
4b

etc..

But that 10 needs to be after the 9, not before the 1, how is this possible?

Thank you, Kind regards

    SELECT 
          CAST(title AS UNSIGNED INTEGER) AS ORDER_FIELD
          ,title
    ORDER BY
          ORDER_FIELD ASC
