Thanks Rob, It helped. I did the option you wrote (with one level referencing) and it worked. 
void add_nir(int x, int y, AV * perlList) {
    SV* perlItem=newSViv(2);
    av_push(perlList, perlItem);
}

I understand that I shouldn't have initialized the AV* inside the cpp code, but only outside in the perl code as you did. Thanks again!
