Orientation Constraint with "Keep intial Offset"

I am in a bit of a bind. I am writing a script that takes an existing rig controls and hooks it up to an existing rig. Problem is that whoever set up the initial rig, did not align anything. They used "Keep Initial Offset" when adding targets to to eliminate the flipping that occurs when two objects are not aligned. The problem is when I add the orientation constraint in maxscript, the controlled object flips. If I align the objects in my script the wrong axis is accessed when I exercise the controls. I see no option in maxscript to flag "Keep Initial Offset" when adding Orientation Constraint. Is there a scriptable option to do this without having to re-rig the whole character? Thanks.
