Command block filters work incorrectly at x=100000 and z=100000

I'm making survival/adventure world for my friends and I'm using lots of scoreboards and things with command blocks =D

What I expected to happen was...:
It should only detect on x=0 y=65 z=0 r=3

What actually happened was...:
It also detects me at x=100000 z=1000000 (and more) and it instantly teleports me
