In short, on_key_press don't do autorepeat, look at pyglet programming guide
in the section 'working with the keyboard'.
You have two alternatives:
a. track yourself the key state, as you can seen in the example posted at
http://thread.gmane.org/gmane.comp.python.cocos2d.user/684
(look the attach in the second message)
b. read the pyglet docs about keyboards, it is possible to query the keys
state at each time.
