  1. Do it like shown below, as suggested by @gyo and done by @Howdy_McGee in his answer.

    function admin_queue( $hook ) {
        global $post; 
        if ( $hook == 'post-new.php' || $hook == 'post.php' ) {
            if ( 'targeted-posttype' === $post->post_type ) { 
                wp_enqueue_script( 
                    'custom-title-here', 
                    bloginfo( 'template_directory' ) . '/scripts/custom-script.js', 
                    'jquery', 
                    '', 
                    true 
                );
            }
        }
    }
    add_action( 'admin_enqueue_scripts', 'admin_queue' );
