[animating scale and opacity]

scale is a property to be tweened by CSSPlugin and should be inside the css object

(with GSAP 1.8, you can also skip the css object altogether if you want)

TweenMax.to($(this), .2, {css:{scaleX:0.8, scaleY:0.8, opacity:0.7}});
// or
TweenMax.to($(this), .2, {scaleX:0.8, scaleY:0.8, opacity:0.7});

I think the mixing of styles is what caused your issue.
