My guess is that MathUtils.random is inclusive, which means that in your example (array of size 12), it will generate a number from 0 to 12, including 12. Try changing your code to:

pItem.setCurrentTileIndex(MathUtils.random(0, pItem.getTileCount() - 1));

try: pItem.setCurrentTileIndex(MathUtils.random(0, pItem.getTileCount()-1));

getTileCount() likely returns the # of tiles, so indexes would be that minus 1.
