I think I have it running now but you have to wait for an update (one of 
those curious border cases where tex bends a rule by turning tabs into 
spaces (the alternative is to let the tab token flagged as spacer travel 
around which would permits round trip). Makes me wonder I should have 
that as option in luametatex (but as I'm now in metapost mode I delay 
that pondering.)
