It is ``trap <action> <signal>'' so for the signal part this may be
right that this is made uppercase. But action is not modified I guess.
So it should be exit because there is no built-in named EXIT in
bash:

$ type exit
exit is a shell builtin
$ type EXIT
bash: type: EXIT: not found

So for me it does not seem to work:

$ trap 'err=$?; echo trap; EXIT $?' 0
$ exit 5
exit
trap
bash: EXIT: command not found
[1]    12906 exit 5     bash
