Order Displayed Child Pages (using get_template_part) on Parent page

Hi,
I found this great explanation: Displaying Child Page (And Template) On Parent and it works great for loading dynamically child pages to the parent page, using custom template parts for each child page.

Problem I found with this, it does not order the template parts ones imported to the Parent page! Please, is there someone that could help solve this?

I will copy over part of the original post and replace it with my code:

…create a Child page with a custom page template create another (content) template as well. You could put the whole loop in there or only the part that’s inside the loop. For example for a child page with a custom page template filename (layout_1col_visualeditor.php) create a template file (layout_content-layout_1col_visualeditor.php).
And on the custom page template (layout_1col_visualeditor.php) include the file like so:

<?php
/*
 * Template Name: Child Page - Layout 1col Visual Editor
 */
?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'layout_content', 'layout_1col_visualeditor' ); ?>
<?php endwhile;?>

Now you can include the get_template_part on the Parent page (layout_loader-page.php) like so:

<?php
/**
 * Template Name: Parent Page - Section Layout Loader
 */
?>
<?php get_header(); ?>

	<!-- CONTENT WRAPPER -->
	<div id="content_wrapper" class="single_pages clearfix">

	<?php
	global $wp_query;

	// is Page a parent page
	if ( $post->post_parent == 0 ) {

		// on a parent page, get child pages
		$pages = get_pages( 'hierarchical=0&parent=' . $post->ID );

		// loop through child pages
		foreach ( $pages as $post ){

			setup_postdata( $post );

			// get the template name for the child page
			$template_name = get_post_meta( $post->ID, '_wp_page_template', true );
			$template_name = ( 'layout_loader' == $template_name ) ? 'page.php' : $template_name;

			// default page template_part content-page.php
			$slug = 'page';

			// check if the slug exists for the child page
			if ( locate_template( 'layout_content-' . basename( $template_name ) , $load, $require_once ) != '' ) {
				$slug = pathinfo( $template_name, PATHINFO_FILENAME);
			}

			// load the content template for the child page
			get_template_part( 'layout_content', $slug );
		}
	}
	?>

	</div>
	<!-- END CONTENT WRAPPER -->

</div>
<!-- END MAIN WRAPPER -->

<?php get_footer(); ?>

And just in case, I copy also the code for the included child page (layout_content-layout_1col_visualeditor.php):

<section class="visualeditor">

	<!-- content block -->
	<main>

		<article class="clearfix">

		<h2><?php the_title(); ?></h2>
		<div><?php the_content(); ?></div>

		</article>

	</main>
	<!-- end content block -->

</section>

Thanks for your help in advance!
