title: Woocommerce - Different 'default' sorting for different categories
body: <p>I'm trying to override the default sorting option (from settings), to a price based sorting for a few categories where lowest price products should be at the top.</p>
  
  <p>For this I'm trying with </p>
  
  <pre><code> if ( is_product_category( 'shirts' ) ) {
      add_filter('woocommerce_get_catalog_ordering_args', 'tk_woocommerce_catalog_orderby');
  function tk_woocommerce_catalog_orderby( $args ) {
      $args['orderby'] = 'price';
      $args['order'] = 'asc'; 
      return $args;
  }
    }
  </code></pre>
  
  <p>But, it's not working. What's missing?</p>
  
  <p>How can we achieve Price based (lowest to highest) sorting for specific categories in Woocommerce 2.1.x ?</p>
  
  <p>Thanks</p>
