Default [Q] Aroma installer sometimes works and sometimes doesn't why?

Hi,

I'm using latest aroma installer for my volume mod posted here. I uploaded it and it worked great, but later I realised that it doesnt work on some recoveries/kernels and I have no idea why. I've read the rules and this board is for me. I actually want to learn WHY it sometimes didn't work and what I've done wrong. Also some tips on how do I add a new menu (not a new checkbox etc.).

I've tried to understand it myself, but I couldn't.

Thanks for any help.
