I haven't tried this myself, but the execute_process documentation says:

"Runs the given sequence of one or more commands with the standard output of
each process piped to the standard input of the next.  A single standard
error pipe is used for all processes."

So I think

COMMAND svn info
COMMAND grep \"Last Changed Rev:\" 
COMMAND  cut -d: -f2

should do what you want.
