How get the 10 most viewed pages (not post)

If you want to query pages you have to choose post_type=page – of course.

Another “problem” is that the commen count isn’t exactly representing post/page views. If you really want page views – not comment count – try something like the function below – I got that from here: http://wpsnipp.com/index.php/functions-php/track-post-views-without-a-plugin-using-post-meta/.

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return "0 View";
    }
    return $count.' Views';
}
function setPostViews($postID) {
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}

With that you would have to query for the new meta key post_views_count. That’s all – good luck!
