[launchd-dev] 32-bit Command Line Tool and Launchd on Lion

I've come across a bit of a stumper. I've got a LaunchDaemon that runs a script every hour. I've updated the script to include a command line tool from a third party, but the tool's architecture is i386 only. When I run the command in the terminal, as root, after using sudo -s it works fine. If I run the command in the terminal using /bin/sh [command] it fails with a "cannot execute binary file" error. If I run the command in the terminal using /bin/sh -c [command] it works. However, if Launchd runs the script the command fails, but all other commands in the script work perfectly. I suspect an evironment issue, but I can't figure it out. Help?
