I also cannot reproduce this problem. I've tried clicking the install button ~30 times with the window in various states and between restarted software-store and the window always pops up above the application. It used to have this problem for me in older versions of compiz.
What version of compiz do you have? ($ dpkg -s compiz), I have:
1:0.8.3+git20090917-0ubuntu1
