perhaps the addr:floor is good, as that will conform to it’s referred to 
location The mail delivery doesn’t give a crap if the building has an odd 
number scheme - it follows the numbering scheme of the location. 

But as I think about it, a  shop may not have it's floor location referenced in 
it’s address - like  a shop in space # 12 on the 3rd floor may simply be #312 
on the address line,

and

as you say, the floor numbering scheme may not line up with the building levels 
(a building may have missing floor numbers due to superstition or oversized 
floors counted as 2-3 floors for residential unit height sales (higher floor 
numbers sell for more money). One of the trump buildings is “missing” 10 
floors, because the lower floors for retail are oversized and counted as 1.5 
floors each. 

this means we might want to use level:ref=*   most shops reference their level 
with an “f” attached:  Uniqlo 4F  (4th floor) - and using the locations label 
sceme is the best. And some places have 1/2 floors - like the “mezzanine" floor 
at many convention centers, or “lobby” “P3” etc. This would allow for these 
non-numbered values to be used (and rendered/used by data providers) in the 
future if the location is selected in the map and displayed along with the 
point and name=* rendering. 

so level:ref= seems to be a good idea.
