Comment:

 A better scoring heuristic would be to compute a difference score for each
 standardized component using something like similarity() or levensthein()
 then assign a weighting to each component and sum and normalize the
 result.

 You can also do things like check if pre directional and post directional
 are swapped and not penalize as much for that.

 This comparison can be done between the standardized reference record and
 the standardized request easily because they are both broken into the
 identical field structures. Making the comparison between the
 unstandardized reference record and the unstandardized request is much
 harder and more erroroneous because things like ST. vs SAINT will throw
 off the scoring.
