In recent enough zsh (4.0.1-pre-3 is the latest version) you can use
$pipestatus:

pipestatus <S> <Z>
     An array containing the exit values returned by all commands in the
     last pipeline.

bor@itsrm2:~%> cat /foo/bar | tee
cat: Cannot open /foo/bar: No such file or directory
bor@itsrm2:~%> print $pipestatus
2 0
