   We just need the available options. Do we still need to get the _options_properties(). Although we are hardcoding the widget type here, but I have tested this using radio buttons, and it worked alright. Which means, the widget type and its properties are not important here, and we can skip them.

   I thought, the idea was to make it compatible with commerce_cart_field_attribute_eligible(). But we are adding support for multivalued fields as well. Also, if we are adding multivalued field support, can you please put a comment here, the comment should tell the purpose of using array_map().

Other that that, the code looks alright to me.
