Here is a command I use for setting the system clock on OS X.
It builds a multi-line set of shell commands, including the su
password, then sends them to the Rev shell() function as a single
command.

on setClock pPassword, pDate, pTime
   -- build the command lines
    put "#!/bin/sh" & cr into tScript
    put "pw=" & quote & pPassword & quote & cr after tScript
    put "echo $pw | sudo -S date " & pDate & pTime & cr after tScript

    -- do the command & get the result
    put shell(tScript) into tCheck
end setClock

To alter to use your command, change the following line:
    put "echo $pw | sudo -S date " & tDate & tTime & cr after tScript

Leave everything up to & including the -S, then put your command &
it's parameters in place of my date command.

HTH,
