It's not too hard; think about it. The rendered text are just a bunch of 
surfaces, and surfaces are rectangles with a width and a height. The 
horizontal centre of any rectangle is half its width.

So work out half the width of the surface, and take it away from the x 
coordinate. Then the x-coordinate will represent the position of the *middle* 
of the text, not the upper left corner.

x, y = 100, 0
for (name, score) in highscore_list:
	text = font.render("%s - %d" % (name, score), 1, (255, 255, 255, 0))
	w = text.get_width() / 2.0		# w = centre of text
	screen.blit(text, (x - w, y))	# (x, y) becomes (x - w, y)
	y += text.get_height()

If you want all the high-score's in the middle of the page, you need to work 
out the centre of the screen. Again, just divide the width by 2:

x, y = screen.get_width() / 2.0, 0
