Have a look at [1] and you will see rules like:
n in 0..1
n is 2
n mod 10 in 3..4,9 and n mod 100 not in 10..19,70..79,90..99
Long ago when I wanted to compare the plural rules of MediaWiki and
CLDR I wrote a parser for the CLDR rule format. Unfortunately my
implementation uses regular expression and eval, which makes it
unsuitable for production. Now, writing parsers is not my area of
expertise, so can you please point me how to do this properly with
PHP. Bonus points if it is also easily adaptable to JavaScript.

You may already know this, but santhosh is working on a parser[1] in javascript
(as a node module, to be specific). I added a test suite to his repository. Ready
to be expanded and build upon!

Would be nice if there was an official test suite to use as input for it, so we don't
have to maintain the test suite manually.
Also useful link, syntax specification:
