With only this information I would have to guess that even though you
have a command that it doing the chmod one way that there must be
another command that is changing it back.

Try running with 'bash -x ./setuid_test_script.sh' in order to trace
your script commands.  I expect to see that there is another one that
you are not expecting that is running.
