It works 100% of the time for me but you MUST hit Alt first then Shift. If you hit them at the same time or use Shift first it will not select it. I use the Selection tool (not direct selection) and the use Alt to duplicate. You'll notice your cursor turns from a single arrow to a double, once it does that you can hit Shift and it will align properly.
