Filter Custom Post Type Posts by Taxonomy

I created a custom post type named “listas” and a custom taxonomy named “taxolistas”.

I would like to fix this function from the plugin Thumbs Rating to make it filter posts by custom taxonomies from Custom Post Types.

Thanks in advance.

if (!function_exists('thumbs_rating_top_func')):
    function thumbs_rating_top_func($atts)
        {
        $return = '';

        // Parameters accepted

        extract(shortcode_atts(array(
            'exclude_posts' => '',
            'type' => 'positive',
            'posts_per_page' => 5,
            'category' => '',
            'show_votes' => 'yes',
            'post_type' => 'any',
            'show_both' => 'no',
            'order' => 'DESC',
            'orderby' => 'meta_value_num'
        ) , $atts));

        // Check wich meta_key the user wants

        if ($type == 'positive')
            {
            $meta_key = '_thumbs_rating_up';
            $other_meta_key = '_thumbs_rating_down';
            $sign = "+";
            $other_sign = "-";
            }
          else
            {
            $meta_key = '_thumbs_rating_down';
            $other_meta_key = '_thumbs_rating_up';
            $sign = "-";
            $other_sign = "+";
            }

        // Build up the args array

        $args = array(
            'post__not_in' => explode(",", $exclude_posts) ,
            'post_type' => $post_type,
            'post_status' => 'publish',

            'order' => $order,
            'orderby' => $orderby,
            'ignore_sticky_posts' => true
        );

        // Get the posts

        $thumbs_ratings_top_query = new WP_Query($args);

        // Build the post list

        if ($thumbs_ratings_top_query->have_posts()):
