Wow I had no idea TP sold that well. Well I'm not sure I'd include the 3DS version in because essentially it is no longer a port but a remake. I mean the 3D and such makes it an entirely different game. Where as the Wii and GC versions are both esentially the same game.
However I agree with others you need to count the VC release and the GCN disk. OoT has alot of ports you need to consider. If you consider all the ports then their is no way TP will beat OoT any time soon.
I think once Skyward Sword gets released Nintendo should cut TP's price to 29.99$, or bundle it with the Wii. Nintendo has a chance to keep the LOZ name as big as possible. I bet if Nintendo cuts price or bundles then it will pass this 300k mark easy.
