Answer 1

I was able to sort this issue with add_filter('pre_get_posts' ::: In essence this is what my script now looks like :::

function laudes_order( $wp_query ) {

        $wp_query->set('meta_key', 'authors_name');
        $wp_query->set('orderby', 'meta_value');
        $wp_query->set('order', 'DESC');

}

add_filter('pre_get_posts', 'laudes_order');


$args = array(
    "post_type" => "portfolio",
);


$custom_query = new WP_Query( $args );
