This as well as the two other online-related trophies can be easily acquired with a friend.
It certainly helps if you and your friend are very close in skill points (when I did it, my friend and I never played a single online game yet). Since these are ranked games, you can ONLY do it through Quick Match. All I did was have my friend and I search for a game at the exact same time and we got matched up on the first try, this was when only a few hundred people were playing online, I imagine trying this at "off hours" would help more.
Then we just traded TDs back and forth until we both had more than 34 points and ran the clock out on the rest of the game, all three trophies will unlock once the game is finished.
Even if you aren't able to do this with a friend, the score-related trophies shouldn't take more than 4-5 games since the score is cumulative, you do NOT need to score that many points in a single game.
