not working with my Custom query

hello, i have a query to get all categories then display all posts in each term
the plugin was working 100% before i create Parent/Child categories.

could you help me where i should put this code ? ‘orderby’ => ‘term_order’, ‘order’ => ‘ASC’

<?php

	//show duplicates
$do_not_duplicate = array(

);
//get all categories then display all posts in each term
$taxonomy = 'category';
$param_type = 'category__in';
$term_args=array(

);
$terms = get_terms($taxonomy,$term_args);
if ($terms) {
        $counter = 1;
		$total_invitations=0;
		$total_invitees=0;
		
  foreach( $terms as $term ) {
    $args=array(
      'post__not_in'     => $do_not_duplicate,
      'connected_type' => 'post_to_event',
      'connected_items' => get_queried_object(),
      "$param_type" => array($term->term_id),
      'nopaging' => true,
      'post_type' => 'post',
      'post_status' => 'publish,draft',
      'posts_per_page' => -1,
      'caller_get_posts'=> 1
      );
    $my_query = null;
    $my_query = new WP_Query($args);
	
    if( $my_query->have_posts() ) {
	$cat_invitations=$my_query->found_posts;
	$cat_invitees=0;
	$do_not_duplicate[] = get_the_ID();	
	?>
<h1><?php echo $term->name;?></h1>
   
		    <?php
     if( $my_query->have_posts() ) {

    while ($my_query->have_posts()) : 
	$my_query->the_post();

        $post_id = get_the_ID();

        if (in_array($post_id, $do_not_duplicate)) {
            continue; // We've already seen this post ID, so skip the rest of the loop
        }

	  if (p2p_get_meta(get_post()->p2p_id, 'couples', true) == '1') $cat_invitees+= 2;
	  else $cat_invitees++;

        $do_not_duplicate[] = $post_id;

        ?>

      <?php include (TEMPLATEPATH . '/contactfullname.php'); ?> - <?php echo get_post_meta($post->ID, 'ecpt_position', true); ?>

	  <?php $counter++; ?>
       <?php
      endwhile;
	  $total_invitees+=$cat_invitees;
	  $total_invitations+=$cat_invitations;
      } ?>
	  
<?php echo $cat_invitations ;?>
			<?php echo $cat_invitees ;?>
<?php
    }
  }
  
 } wp_reset_query();  // Restore global post data stomped by the_post(). ?>
