That might be the way I’d go if I had to do it as well. Quite honestly the whole array_multisort thing hurts my head.

For the future for anyone that finds this, I did find an alternate solution, you could also try using usort() http://php.net/manual/en/function.usort.php.

// get the entire repeater in a multidimensional array
$repeater = get_field('repeater');
usort($repeater, 'sort_by_email');

// usort function
function sort_by_email($a, $b) {
  if ($a['email'] == $b['email']) {
    return 0;
  } elseif ($a['email'] < $b['email']) {
    return -1;
  } else {
    return 1;
  }
}
