Sort Most Liked Posts in custom query?

Hi. No doubt this is the best like/unlike plugin and I like it a lot. But I’m having trouble implementing the sort feature in my custom query and I’ll appreciate any help.

This my default custom query:

$heroes_query = new WP_Query(
array(			
    'posts_per_page' => 3,
    'post_type' => 'heroes',
    'order' => 'DESC'
    )
);

And this is what I tried and no luck:

$heroes_query = new WP_Query(
			
    array(		
        $post__in = wp_ulike_get_popular_items_ids(array(
            'type'   => 'post',
            'status' => 'like',
            'period' => 'all'
        )),	
        'posts_per_page' => 3,				
        'post_type' => 'heroes',
        'post__in' => $post__in,
        'orderby' => 'post__in',
        'order' => 'DESC'
    )
);
