Variable sets are not ordered correctly against the order field.
Variable sets follow the order field on the variable set table (item_option_new_set), rather than the table that links variable sets to catalog items (io_set_item). Therefore, the order field on variable set related list does not work.
Variable Set is ignoring Order
Steps to Reproduce
Use the order field on the variable set form (item_option_new_set). This does affect other catalog items that use the same variable set.
