Hi,
Having a quick look, if you use the -f switch. Then I think that /usr/bin/expect -f ${expect_commands_file} is what is expected.
If you create an expect script starting #!/usr/bin/expect containing the code - think that you'll get on better - also I'd be tempted to make an explicit call to it and to put some error checking in the control script.
