Given that there hasn't really been anything you could call an 'official' version of Scots since James VI headed south, it is of course difficult for the parliament to produce something completely acceptable to all of the regional variations of Scots, so we won't be too hard on them. But considering the number of native Scots speakers is estimated as in excess of 1.5 million, while the 1991 census identified only 67,000 speakers of the one everybody's heard of, Gaelic, then there's an inexorable logic to the language getting the Parliament's support.
