Check the code.
Until Ora9i when you had a GROUP BY clause ORDER BY was implicit meaning Oracle would sort the output by the GROUP BY condition even if no ORDER BY was explicitily specified.
Starting on Ora10g if you want to ensure the output sorted you have to include both GROUP BY and ORDER BY clauses.
