It does not matter which side an IR Cut filter is placed in the stack. I've tried both sides with a Hoya IR Cut and the GenusTech Eclipse ND Filter.
It does matter if you use a HotMirror IR filter. These filters reflect the light back and you get internal reflections that do horrid things with your image.
