Or, if you prefer to avoid fifos:

test.sh:
  #! /bin/sh
  echo "standard output" >&1
  echo "STANDARD ERROR" >&2

This command will do what you want, I guess (at least in bash):
$ (./test.sh | tr a-z A-Z) 3>&1 1>&2 2>&3 | tr A-Z a-z

The first "tr" receives stdout as input, and the second one receives
stderr as input.
Take care of one thing: The current state of stdout/stderr is messed up
then. You may want to restore them, in case you have another pipe
following, for instance:
$ (((./test.sh | tr a-z A-Z) 3>&1 1>&2 2>&3 | tr A-Z a-z) 3>&1 1>&2 2>&3)
