It suid bit controls the switch of the effective uid. The sticky bit has nothing to do with it. And modern kernels will ignore the suid and sgid bits when executing scripts.

There is a program called "sudo" that can let a user run a script with another uid's authority. That is what I would recommend. sudo is a public domain program available from various archive sites.

NAME
fdutilsconfig - configure the suid bit of fdmount SYNOPSIS
fdutilsconfig DESCRIPTION
The fdutilsconfig script provides an interactive way to configure the suid bit of the fdmount(1) binary. It asks you some questions, give you a hint if needed, and enters your choice to /etc/fdmount.conf file. When upgrading the Debian fdutils package, the suid bit information stored in /etc/fdmount.conf is used to tell the new fdmount binary to keep your old suid bit settings. The script makes use of the suidmanager Debian package, if it is installed. If the script cannot find it, it manipulates the suid bit directly via `chmod u+s' command. FILES
fdutilsconfig reads and writes the configuration from /etc/fdmount.conf. This file is usually created when the fdutils package is installed for the first time. Please don't edit /etc/fdmount.conf manually! Use fdutilsconfig instead. NOTE
This script was written exclusively for the Debian GNU/Linux distribution. It is not a part of the upstream fdutils sources. AUTHORS
fdutilsconfig was adapted by Anthony Fok <foka@debian.org> from the gnuplotconfig script written by Tibor Simko <simko@debian.org>. SEE ALSO
