Because of the way sudo and/or bash works with redirection, you're
basically trying to output the result of "sudo echo 1" to
/proc/whatever. I forget the way to get around this, but I'm sure
someone with more knowledge than I will figure it out.

Also, handy hint to get the effect of su using sudo: sudo bash.
Instant root shell.
