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
viewsudo - execute a command as another (virtual) user SYNOPSIS
viewsudo [-g groupname|#gid] [-u username|#uid] command DESCRIPTION
viewsudo allows a user to execute a command as the superuser or another user in View-OS. OPTIONS
viewsudo accepts the following command line options: -g group Normally, viewsudo sets the primary group to root. The -g option causes sudo to run the specified command with the primary group set to group. To specify a gid instead of a group name, use #gid. When running commands as a gid, many shells require that the '#' be escaped with a backslash ('[u2019]). If no -u option is specified, the command will be run as the invoking user (not root). In either case, the primary group will be set to group. -u user The -u option causes viewsudo to run the specified command as a user other than root. To specify a uid instead of a user name, use #uid. When running commands as a uid, many shells require that the '#' be escaped with a backslash ('[u2019]). RETURN VALUES
Upon successful execution of a program, the exit status from viewsudo will simply be the exit status of the program that was executed. SEE ALSO
