I both agree and disagree with you on this one.

Your position on what it takes to get into Scion is definitely accurate. Being a bad-ass certainly makes it easier, as does being able to regurgitate prep/quest info (any cabal leader who makes quest/prep info questions a major part of their is a douche bag, btw).

That said, my last Scion was inducted after simply being a decent pledge for a little while and going through a relatively painless interview.

It all depends on who is the leader at the time. Often times though, I think the easiest way to get into Scion is simply to A) do your job as a pledge correctly, and B) don't make yourself seem like your character should automatically be inducted just because it's played by a player who has or had the chops to play Scion. Unlike real-life, past jobs have nothing to do with your (IC) qualifications for getting in a cabal, and it seems to irk plenty of leaders who someone comes to them as basically says, "Yo, Scion is how I roll. Let me in, dawg."

That's my humble two cents on the matter.

PS: Again, PK chops and all the requite skills and knowledge to have said PK chops are definitely necessary to play a Scion out, and most likely just to get in too.
