block match gets same score as street address with locality alias which causes confusion

7460 heather st vancouver bc

is not known to the geocoder but the geocoder does know the 7400 block of heather st in vancouver.

7460 heather st richmond bc

is known to the geocoder so when you enter 7460 heather st vancouver bc, both addresses get a score of 99 but the richmond address just happens to come up first in autocomplete. This is very confusing and will give the wrong address in the batch geocoder.

Perhaps the penalty for locality aliasing needs to be increased to 2? What effect will this have on other matches?
