It seems you try to get the real distance (taking into account the greater distance in diagonals).
Why don't you get the real distance from the very beginning then?
That is, replacing getManhattan by

Function getRealDist(this.tile, where.coord)
	mX = this\x - where\x
	mY = this\y - where\y
	mZ = this\z - where\z
	Return Sqr(mx*mx + my*my + mz*mz)
End Function

I confess I have not looked deeply at your code, but I guess that's what you want to achieve.
NB: I also removed this " * 1 " (!?!)
