Sorry to have disturbed some, the answer was in Python.
Instead of writing directly the grid rows, it is is possible to build a dictionary having as keys the content of cells in the sorting column, and as values the values of the other cells of the row. Then you sort the keys with the built-in function «sorted», and fill the grid from the dictionary.
It wasn’t my brightest day.
