When installing insulation the paper side, or vapor barrier side, should face the "warm in winter side". Insulation installed improperly can cause moisture to build up in the insulation and then promote the growth of mold and it will not insulate as well.
sorry, today that paper is a vapor retarder......NOT a vapor barrier......do you actually have mold problems? Heat a vapor rise, plus batting works best when there is an air barrier on both sides, if you were to flip them over, you would probably lose a bit of R-value...it is usually not considerd a retarder or barrier if they are not sealed(continueous), since the sides are loose, the only way I could see having moisture problems is if your garage floor is allowing too much in.
