Вот ещё вариант

Код:

procedure SortToTableDesc(StrGrid: TStringGrid; SortColumn: integer);
  function Uslovie(s2, s1: string): boolean;
  var vl1, vl2:Extended;
  begin
    if tryStrtoFloat(s1,vl1) and tryStrtoFloat(s2,vl2) then
       Result:= vl1 > vl2 else Result:= s1 > s2;
  end;
var i, j, k: integer;
  sTemp: string;
begin
 with StrGrid do
  for i := FixedRows to RowCount-2 do
   for j := i + 1 to RowCount-1 do
    if Uslovie(Cells[SortColumn, i], Cells[SortColumn, j]) then
     for k := FixedCols to ColCount-1 do
      begin
       sTemp:= Cells[k, i];
       Cells[k, i]:= Cells[k, j];
       Cells[k, j]:= sTemp;
      end;
end;
