New plural rules for Scots Gaelic (gd)

Ok, thanks for the quick replies. I didn't realise there was a ruleset already.

I'll open a ticket with CLDR though I've been warned of their response speed ;)

Beyond that, the current LanguageGd.php is unnecessarily inadequate by claiming that "above 10 it gets messy" or "isn't that important". It's true in most languages that there's a certain amount of variation the spoken language gets away with but that does not mean you cannot codify one standard model. I can produce sources galore, what do you have in mind?
