When you run it in a script like that, you fork a subshell to run the
script. It runs just fine. Insert an echo $IA32ROOT statement in your script
and you will see it. But when the script ends, so does the subshell.

It's apparently your desire to set the value of that variable in your
running shell. To do that, "source" the script by running it with the "."
(dot) command:

. ./test.sh

should do it for you.
