Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HHH-892
    Summary: HQL parser does not resolve alias in ORDER  BY clause
       Type: New Feature

     Status: Unassigned
   Priority: Minor

 Original Estimate: Unknown
 Time Spent: Unknown
  Remaining: Unknown

    Project: Hibernate3
   Versions:
             3.0.5

Environment: Hibernate 3.0.5, MySQL, Tomcat

Description:
When using an alias for an ORDER BY clause this is not always correctly resolved. Example:

SELECT SUM(A.x) AS mySum FROM MyClass AS A GROUP BY A.y ORDER BY mySum

does not work because "mySum" is not resolved in the ORDER BY clause which results in an exception telling that mySum is an unknown column.

Workaround (not to say "hack") is using:
SELECT SUM(A.x) AS mySum FROM MyClass AS A GROUP BY A.y ORDER BY col_0_0_
