Typically used Old School errata:

Chaos Orb
2
Artifact
1, Tap: Choose a nontoken permanent on the battlefield. If Chaos Orb is on the battlefield, flip Chaos Orb onto the battlefield from a height of at least one foot. If Chaos Orb turns over completely at least once during the flip, and lands resting on the chosen permanent, destroy that permanent. Then destroy Chaos Orb.
(Note: because of how Chaos Orb is worded, with it being destroyed after a flip, it can still be Disenchanted or Shattered in response to the activation. This is consistent with the wording of Chaos Orb not being sacrificed upon activation, as it probably would with modern templating.)

In a commonly used Old School ruleset, it says:

No Draws in EC Tournaments

In order to encourage the maximum amount of Magic and matches being played (and disincentivize draws and concession for seeding), we enforce a strict no draw policy (intentional or otherwise). After 50 minutes if there was a tied match, the tie breaker will be a sudden death Chaos Orb flipping contest, similar to a hockey or soccer overtime shootout. If both players make or miss the Chaos Orb flip in the same round, repeat the process. The first person to make it while the other person misses will be declared the winner of the match. The point of Old School is to play Old School, so we always encourage everyone to play quickly and have fun each round, and this tournament structure has worked very well to that end.

tl;dr
If the game would end in a draw, a Chaos Orb Flip contest is done instead.

My question:
Are tournaments using this method still sanctionable as Casual events ? Or: Can you run events without applying JAR / IPG ?
