Hi Gabriel,
the featured products shortcode of Woocommerce order the featured products by date, which can be found here: http://docs.woothemes.com/document/woocommerce-shortcodes
So if you ever need to change the order, just change the date of the order by.
Example: [featured_products per_page=”12″ columns=”4″ orderby=”order” order=”desc”]
Hope it helps.
