Query Google Sheets Using Week Num to order dates

I was finishing ordering timestamps and dates, and I can't quite get it to work:

=QUERY(Sheet3!A:I, "SELECT D, SUM(I)  GROUP BY WEEKNUM(D) ORDER BY D DESC  LABEL SUM(I) 'Balance Semanal'        SUM(I) '$#,##0.00'")

Please let me know your thoughts on how to fix this.
