Group by rollup and order by question

Question

hi all,
normally, using order by would sort data based on the column. however, i am using a group by roll up with an order by and my select case contains some case grouping... see my code below.
SELECT
  CASE GROUPING(org) + GROUPING(sbu)
    WHEN 2 THEN 'Grand Total'
    WHEN 1 THEN NULL
    ELSE NULLIF(org, 'ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ')
    END org,
  CASE GROUPING(org) + GROUPING(sbu)
    WHEN 2 THEN NULL
    WHEN 1 THEN 'Total'
    ELSE ipl_rep_sylk_pkg.get_sbu_name(sbu)
    END sbu,
  SUM(ft) ft,
  SUM(pt) pt,
  NULLIF(NVL(SUM(ft),0) + NVL(SUM(pt),0),0) tot,
  NULLIF(NVL(SUM(ter),0) + NVL(SUM(ret),0),0) ter_ret,
  SUM(adds) adds,
  SUM(ins) ins,
  SUM(outs) outs,
  SUM(fft) fft,
  SUM(fpt) fpt,
  NULLIF(NVL(SUM(fft),0) + NVL(SUM(fpt),0),0) ftot,
  SUM(bft) bft,
  SUM(bpt) bpt,
  NULLIF(NVL(SUM(bft),0) + NVL(SUM(bpt),0),0) btot
FROM xxipl_ceo_personnel_tbl
GROUP BY ROLLUP (org, sbu)
ORDER BY org, sbunot sure why but my data always start with the Grand Total Row and ends with all the Total Rows.
is there something wrong with my query?
thanks

You have aliassed your columns with the same name as the original columns org and sbu. Your order by now orders by your aliassed expressions instead of the original columns. And the "G" of "Grand Total" is before the "T" of "Total" in the alphabet ;-)
