Hello Stuart, you might find it easier searching for 'scottish slang' or 'scots slang' rather than just words. I found this site almost straight away. I think this is the sort of thing you're after. http://www.firstfoot.com/php/glossary/phpglossar_0.8/index.php or even the wiki page on scots words http://en.wiktionary.org/wiki/Transwiki:List_of_Scottish_slang_words Even the Scottish Government got in on the act too, though even I'm not sure it makes sense... and I'm a scotsman too! lol http://www.scottish.parliament.uk/vli/language/scots/index.htm Hope these help in your search.
To add to what Conall said above, I think you should note down beside some words that they aren't only used in Scotland.
