I am kind of new to this but have figured out that where you use a css default, i.e. opacity: 0 and then you want to to override with inline css using tweenMax etc, it seems to make more sense to use the .to method.
SO in your case the following worked for me:
TweenMax.to( $('.homeImg>img'), 0.5,
{css:{scale:.05, opacity:1, rotation: 180}, ease:Quad.easeInOut});
