How to use Apple Script to control backlit keyboard?

Question

Is there a way to use an Apple Script to control the brightness of the backlit keyboard on a Macbook?

The backlit keys are the F5 and F6.

Edit:

Based on the suggestion of @Clark I tried the follow, but it does not work.

    NSAppleScript *run = [[NSAppleScript alloc] initWithSource:@"tell application \"System Events\" to key code 96"];
    [run executeAndReturnError:nil];

Any suggestions?

Amit Singh has a chapter on how to do this from C.

It'd be easy to compile the sample code on that page and call it from Applescript.

To make Applescript type a function key you have to use the key code. The key codes fore the function keys are:

• F1 = 122
• F2 = 120
• F3 = 99
• F4 = 118
• F5 = 96
• F6 = 97
• F7 = 8
• F8 = 100
• F9 = 101
• F10 = 109
• F11 = 103

To type one do something like this:

tell application "System Events" to key code 96
