Really? That surprises me. It's been ages since I met an established pair that played 1M-3M as a limit raise.

I don't think it matters much what percentage of players play it as limit raise. 5B5 of the EBU Orange Book, which applies in this case, states:
"If there is no alert and no announcement, opponents can assume that there is no agreement that the call falls within an alertable or announceable category." True, we have the conflicting 5H1:
"A player’s claim to have been damaged because the opponents failed to alert or announce a call will fail if it is judged that the player was aware of its likely meaning and if he had the opportunity to ask without putting his side's interests at risk."
It is unclear which of these take priority, and I see the latter being there to prevent someone stating that he would have doubled 2C if he had known it was Stayman, or would have bid except he thought that a 2NT overcall was natural, not both minors. Note that it says "and" if he had the opportunity ... so it is enough to conclude, as here, that he could not have been aware of its likely meaning as people play it differently. If he did know that the players used pre-emptive raises, then the second test of whether he could safely ask is applied.
As far as the adjusted score is concerned, it is entirely up to the TD to decide, under 21B3, whether the infraction benefited the offenders, and the benefit of the doubt is given to the non-offenders:
"When it is too late to change a call and the Director judges that the offending side gained an advantage from the irregularity he awards an adjusted score."
To overturn the adjusted score, you would need to show that the director's judgement here was wrong, and he might quite easily conclude that a player would be more inclined to bid over a pre-emptive raise. But it does seem that a weighted score is more appropriate, polling, say, ten players and weighting the scores according to the number of peers that bid. To find the peers, we need to find those that pass over a limit raise, so it might be a slow process, like trying to find someone that votes for the Monster Raving Loony Party. Of course everyone bids here.
I prefer to give the lawmakers credit for stating things for a reason - barmar
