The latest version released 2.1 has detailed documentation on the shortcode in the documentation. We do not sort the portfolio by order attribute since some of our users complained about having to reorder everything when they need it to be sorted by date(default behavior). You can change the shortcode to sort by order attribute by making code change in file framework/functions/post-functions.php file at line number 503 to insert the left positioned query attribute –
$loop = new WP_Query(array('post_type' => $post_type, 'posts_per_page' => $post_count,
'tax_query' => array(array(
'taxonomy' => $taxonamy,
'field' => 'slug',
'terms' => explode(',', $terms),
‘orderby’ => ‘menu_order’,
‘order’ => ‘ASC’,
))));
Hope that helps.
