       # does not work
        % perl script 2>&1 > test.out

    I'm not entirely certain why, but when you do that, only what would originally have been sent to STDOUT is redirected to test.out and your warnings will go to STDOUT. Change that to:

    %perl script > test.out 2>&1

        % perl script &> test.out

    Never seen that before, but then, I still don't understand Linux terribly well.

      From man bash:

      Note that the order of redirections is significant. For example, the command

      ls > dirlist 2>&1

      directs both standard output and standard error to the file dirlist, while the command

      ls 2>&1 > dirlist

      directs only the standard output to file dirlist, because the standard error was duplicated as standard output before the standard output was redirected to dirlist.
