Order/Draft Order 'tags' bug - draft_order_tags - is invalid

Hi Shopify,

So I came across a pretty interesting bug today (which took quite a few hours to figure out).


Lets say for instance you have orders already in place with the tag "Special".


If you try and do a "put" into the Orders/Draft Order API with the tag "special" - it will complain with 'draft_order_tags - is invalid' why? Casing matters. If you try and put in 'special' into a Shopify Order via the Admin, it will automatically get converted into 'Special'.

Could it please be tweaked so that we get a more helpful error message, or the same happens via the API? (Maybe with a note in the documentation about this).
