Default No root? Wtf?

I have used some application they need root. But some of them didn't work well. For example: GMD speed time, slash game buster and root checker said I'm not rooted. But it's false. I have rooted 4.0.3 than upgraded to jb than rooted again than unlocked the bootloader than flashed CM 10.2. What is the problem with these apps? Are they just simply not compatible with? Is there anyway to use these?
