I think when you tilt your head - especially up - it allows interaural level and time differences to come into play that arent normally available for vertical soundsources. Basically the sound will hit one ear before the other and louder. We all know thats the case for horizontal sounds - but I think thats why we tilt our head up too. I suspect floor as well as shoulder reflections count !
