I've never heard that before. What do you mean by gravitational forces align? How would we know that they were aligned? By the tides?
Since gravity travels at the speed of light, I imagine that the gravitational forces should align when they appear aligned, which should lag their actual alignment by about 1 second, Light Travel Time from the Moon to the Earth.
The force of gravity is to a very good approximation a true central force - so the Earth is attracted to where the sun is now, in an inertial frame at the center of mass of the solar system (essentially equal to the inertial frame in which the sun is stationary, but not quite). This does not mean that gravity actually travels faster than light, however. See the sci.physics.faq
