i try use here code behind little bit.

  1. give scrollviewer name (like 'x:name="myscrolly"').
  2. listen 'selectionchanged'-event of listview.

  3. in event handler of selection changed event (code behind) call:

    myscrolly.scrolltobottom();

i think new item @ bottom. if not try method: 'scrolltoverticaloffset()'.
