Load all Order with Attributes
Try uc_order_status_list

Parameters:

$scope - Defaults to all, but you may specify the scope for the order statuses you want listed based on their corresponding order state. Possible values are - all, general, specific, or any order state id.

$sql - Pass this parameter as TRUE to alter the return value for a SQL query.

$action - By default, this is empty. Since order statuses are cached, you can pass in 'rebuild' to reload the contents from the database if you are making changes to statuses on a page load.

Return value:
The return value will be either an array of status arrays (containing the keys id, title, state, and weight) or a string containing an array of status ids for use in a SQL query.
