Try--cautiously and gently--to burnish it out? Like etchers burnish steel engraving plates, but you'll have to develop your own sense of what metal is best to rub the titanium, how hard to rub it, etc. I've had to do this, and my own experience was that there's a just-sufficient amount of burnishing, starting with short strokes longitudinally along the edges of the scratch, observing how the worst sticking-up jaggeds respond, which might eliminate the worst of the jagged shadows from the scratch, without creating a noticable, wider, smooth track where the scratch was. But this was like smoothing brass scratched by steel, who knows what titanium looks and reacts like. Or fill it with some epoxy, or wax paste, tinted the right color?
