Made order number be unique only for commerce order type

For example I have 2 commerce_order bundles:

• commerce_order
• invoice

And I need have order numbers like [date:custom:Y]-{id} (like 2014-1) for both of them. And {id} not order_id, it's real id of invoice or of order.
And in this case I can have order_number 2014-1 for both. And in this case I see:

DatabaseTransactionOutOfOrderException: in DatabaseConnection->rollback() (line 1059 of /var/www/erpal3/www/includes/database/database.inc).

So added logic for order_number which can be unique only for commerce_order type.
This not change default logic of commerce but gives possibility to works with different commerce order bundles.
