How to get apps that were taken off the App Store back to ios 6?

I got a new iphone 5 hoping I could get apps that were deleted off the App Store (that I bought) back (such as the semi fake display recorder and mctube) but I have not found a way to get them back. When I go to purchased and not on iphone, they aren't there. I remember when I bought the items and they are not in the history to download. Why is that?

I'm not sure why you would expect them to be there if Apple booted them from their App store.
