As its name suggests, 'rand' is used to list multiple glyph variants that the engine should select from (pseudo)randomly, see: http://www.microsoft.com/typography/otspec/features_pt.htm#rand
For testing, my OpenType implementation of Knuth's Punk font can be a good test: https://github.com/khaledhosny/punk-otf (though it is not a serious font, 'rand' can have good application in calligraphic and fonts that tries to capture irregularities of hand writing.)
