Status update selectbox displayed on admin/store/orders/% is not sorted by status weight

This is because of this part of the code, line 635:

<?php
  foreach (uc_order_status_list('general') as $status) {
    $options[$status['id']] = $status['title'];
  }
  foreach (uc_order_status_list('specific') as $status) {
    $options[$status['id']] = $status['title'];
  }
?>

A quick way to fix it is to add the following after it:

<?php
  $sorted_options = array();
  foreach (uc_order_status_list() as $status) {
    if (isset($options[$status['id']])) {
      $sorted_options[$status['id']] = $status['title'];
    }
  }
  $options = $sorted_options;
?>
