CLONE - testfor command block no player found please review it again i did further testing

the testfor command isn't working correctly:
I tryed "testfor @a[score_(Test)_min=1]" and it doesnt matter what score i had it always told me that there are no players found.
please tell me if you didnt understand or need more information..

edit: the stuff behind the @a is in [] brackets it just turned into a link i dont know how to change this D:

edit: i did further testing and it looks like that only happens to objectives containing brackets pls try to reproduce it again

edit: im to stupid to atach a screenshot maybe its because its not an ingame screenshot but heres a link: http://i.imgur.com/IgcLNsi.png
