You can remove posts with ‘page’ type directly from SQL query.
Add this:

AND post_type = ‘post’

on line 1938. You’ll get something like this:

function get_top_ranked_posts($limit) {
        global $wpdb;
        $temp = $wpdb;

        $join = apply_filters('posts_join', '');
        $where = apply_filters('posts_where', '');
        $groupby = apply_filters('posts_groupby', '');
        if (!empty($groupby)) {
            $groupby = ' GROUP BY '.$groupby;
        }
        else {
            $groupby = ' GROUP BY '.$wpdb->posts.'.ID ';
        }

        $posts = $wpdb->get_results("
            SELECT ID, post_title
            FROM $wpdb->posts
            LEFT JOIN $wpdb->ak_popularity pop
            ON $wpdb->posts.ID = pop.post_id
            $join
            WHERE post_status = 'publish'
            AND post_date < NOW()
                AND post_type = 'post'
            $where
            $groupby
            ORDER BY pop.total DESC
            LIMIT ".intval($limit)
        );

Personally I use akpc_most_popular() function to get popular posts. And it transitively calls get_top_ranked_posts().
