System Information
Windows 7 Professional 64-bit, Geforce 560 Ti video card
I'm unable to test it on a separate computer myself, but it was also experienced by a separate user in http://blenderartists.org/forum/showthread.php?337845-Changing-spot-size-of-spotlight-with-Python-doesn-t-adjust-texture-mapping

Blender Version
Broken: 2.70a (from Blender.org)

Short description of error
As the spot size is modified with the KX_LightObject.spotsize variable, the texture size remains constant. Changing the spot size with the slider in the Blender UI outside of the game engine causes the texture size to change as well, and whatever size is set there is the size it uses in-game.

Exact steps for others to reproduce the error
Open the attached .blend
press P while the cursor is over the 3D view

The light on the left is animated with the script (the spot size changes according to a sine wave), the light on the right is animated with curves to show expected behavior (it moves in and out, animating the spot size with curves doesn't appear work in-game, but the approximation is close enough for demonstration).
While the game engine isn't running, note that you can adjust the spot size of the light on the left, and the texture scale will change, and then remain at that size while the game runs.
Additionally, the Size properties in the texture panel don't have any effect in the viewport or in-game.
