I need some help modifying this script. I am trying to also show related posts by custom taxonomies and custom post types.

//* Define custom image size for featured image in Related Posts
add_image_size( 'related', 300, 0, true );


add_action( 'genesis_after_entry_content', 'child_related_posts' );
/**
 * Outputs related posts with thumbnail
 *
 * @author Nick the Geek
 * @url http://designsbynickthegeek.com/tutorials/related-posts-genesis
 * @global object $post
 */
function child_related_posts() {

        if ( $tags ) {

//* Enqueue and initialize jQuery Masonry script
add_action( 'wp_enqueue_scripts', 'sk_masonry_script' );
function sk_masonry_script() {

    if ( is_singular( 'post' ) ) {

        wp_enqueue_script( 'masonry-init', get_stylesheet_directory_uri().'/js/masonry-init.js', array( 'jquery-masonry' ), '1.0', true );

    }

}

Here are the post types that I have:

1: post (tags, categories)

2: custom_post_type: (4 custom taxonomies)

3: custom_post_type: (2 custom taxonomies)

4: custom_post_type: (1 custom taxonomies)

I was able to make some adjustments by just looking at the code and was able to get custom post types related posts to show up. However, i am sure that there is someone better than I am out there who can make this work.
