sort array

[fabius]

Hi, I want to sort an array (actually it's a table), I mean something like that:
$events [][][][] its a matrix n x 4, and I want to sort it by third column i.e.,
I tried with Sort_Table() but it doesn't seem working.

@events = Sort_Table(
      cols      => '4',
      field     => '3',
      sorting   => 'descending',
      structure => 'single', # I tried whith csv too
      #separator => '\*',
      data      => \@events,
);<

Does anybody know how can I do that?????

Edit: BazB added code tags (again).
