I'm off work for a couple of weeks so can't verify anything, but you can do some checks to find out the cause.
Each time through your loop, instead of using polyColorPerVertex in the if statement, assign its result to a variable, then print it out, then use it in the if statement. Something like: col = cmds.polyColorPerVertex(i, q=True, r=True)[0] print col, col == 0.456 if col == 0.456: etc That will tell you if you're actually getting the colours you expect, and also tell you if Python thinks the value is close enough to 0.456 that it considers them equal. It may be that you need to check if col > 0.456-0.001 and col < 0.456+0.001 because it might be really close but not quite equal.
