Well, I know this one is "...dead, Jim", but perhaps I can answer your second question which is how to do what it is you originally wanted to do. As Gordon pointed out, the redirect is handled by the original shell (Thanks, Gordon. I learned something. One of those, 'Oh yes, of course, I should have known that' moments.) so what you want to do is sudo a new shell and put the redirect in it. I tested sudo sh -c 'cat test >> /tmp/t' which worked for me.
