Peruvian seems most likely, yes... But of course there is more than one Peruvian Quechua...
Well anyway to me this seems Cuzqueno, but I don't know enough yet to be sure, and also haven't really read anything but Cuzqueno and Ayacuchano yet. Ayacuchano I think uses more often the trivocalica writing as does this texts, but doesn't have aspiratives and glottal stops - and in Cuzco the trivocalica is becoming more common too I think.
