I think one of your problems is that you are using strings (text fields) to store numbers, but I’m not sure because you didn’t display the code that is outputting the max value.

I would likely to something like this

$max = 0;
if (have_rows('sales') {
  while (have_rows('sales')) {
    the_row()
    $value = intval(get_sub_field('all_regions_percentage_off'));
    if ($value > $max) {
      $max = $value;
    }
    if (have_rows('different_regions')) {
      while (have_rows('different_regions')) {
        the_row();
        $value = intval(get_sub_field('percentage_off'));
        if ($value > $max) {
          $max = $value;
        }
      }
    }
  }
}
echo $value;
