I think is just a two pole jack. The ground always goes to the pole connected to the inner ring . This connects to the long shaft of the plug. The bent tip of the metal comes in contact with the isolated knob at the end of the plug. On a two pole jack it's always the pole isolated from the center metal part of the jack.

I think I got it right with the arrow colors. However, I got sound plugged in with it connected both ways.

The tabs are about the same size except for the obvious squared end on one of 'em.

The tab connected to the metal inner sleeve is the Ground, the other tab  is the Hot. The other longer metal tab is the contact for the cord input.

Oh!  The dreaded and complicated 3 pole jack!  

Two pole jacks are perfect for an electronics dunce like me.   I recall trying to wire a  3 pole and having to call Gitty for help  - and still not understanding it.  But it worked.  If nobody gives you a good answer, call Gitty on Monday.   (Whether you bought it from him or  not.)
