OK, you said that the 50 lb tank has a siphon, and there may be a stamp or tag on the tank that says so, but it is not true. I have this problem every once in a while. My tanks do not say whether they have a siphon tube or not. I own my tank and just exchange it every time I need a refill. All the tanks look the same but obviously differ internally. Your 3 oz result indicated that the tank DOES NOT have a siphon tube so you need to turn the tank upside down. I made a mount on my wall so I can setup either upright or up-side-down. 

Procedure, as you probably already know, is to charge the 20 oz tank with  (while hanging on the scale) 6 to 8 oz of CO2. Close the 50 lb manifold valve and crack open the bleed off valve and let the 20 oz cylinder blow off until the weight drops 2 oz or so. The 20 oz tank should get frosty cold. Repeat the fill from the 50 lb and it should go easily to 1 lb 4 oz. If it doesn't, bleed off another ounce or so and refill again.

Be aware that when everything is right you can actually get three or four additional ounces into the 20 oz bottle...which may promptly blow out the rupture disk when the tank warms up in a sunny car...been there, done that. A new copper blowout disk costs at least half as much as a new 20 oz cylinder, so there is no economy in trying to overfill. I actually would fill my 20 ouncers to 1 lb to avoid loosing a cylinder left in a car...they'd blow right when I really needed that cylinder for the next game.
