Set order of returned items in the WP_Query() class/function

sort_column is not a valid parameter for WP_Query. You want orderby. sort_order is also not a valid parameter. It should just be order.

$all_wp_pages = $my_wp_query->query(
    array(
        'post_type' => 'page', 
        'order' => 'ASC', 
        'orderby' => 'menu_order'
    )
);
