Category filter

Perfect day for all :-).

Please, I have a trouble with filtering post by category. I filter it, but the sorting by post view count doesn´t work. How can I solve it?

It´s my code:

$r = new WP_Query( array(	'posts_per_page' => $number,
									'cat'=>$_POST['category_id'],
                  'no_found_rows' => true,
									'post_status' => 'publish',
									'ignore_sticky_posts' => true,
									'meta_key' => $meta_key,
                  'meta_value_num' => '0',
									'meta_compare' => '>',
									'orderby'=>'meta_value_num',
									'order'=>'DESC',
									'author'=>$author_id,
                  'category__not_in'=>'208',
									'post_type'=> apply_filters( 'baw_count_views_widget_post_types', $bawpvc_options['post_types'] )
								)
						);

In POST is number of category page, which call the loop of posts.Please much, I spend all week of testing different query.
