All of 46B is qualified by "except when declarer's different intention is incontrovertible". There is an example from Ton Kooiman, I think in the White Book, where declarer had KJx in dummy opposite xx in hand and said "any". He was deemed to mean "either the king or the jack".
You misquote Ton in a significant way. In Ton's example, declarer actually thought for a while and then said "I don't know, play one". I think it is that very specific context that allows Ton to conclude declarer incontrovertibly meant "one of the two honours". If instead declarer had just quickly said "any", I don't think that incontrovertible conclusion remains available, rather alternative explanations are available. He may have come to the erroneous conclusion that AQ is likely lying over the KJ, and thus it really doesn't matter. Or he may have miscounted his tricks and think that two down is unlikely much different from one down, so it doesn't much matter for that reason.
When declarer says "any" meaning "any", and in fact it makes a difference, declarer has either made a mistake, or else lost interest. In such cases, rare as they are, I have no scruple in requesting the losing play, as some others have said above.
Lamford asks "Teams; Contract 4♥ by South. Lead Q♦.
Another thread "play one" reminded me of the above hand, with average players at a local club. West led the ♦Q and declarer won, drew trumps and led a spade towards dummy. When West played low, declarer said "any" and East, who behaves like the Secretary Bird, pounced and requested the eight be played. The TD had to decide whether declarer's incontrovertible intention was to play the ten or jack. SB argued that declarer might not have noticed the nine was missing, and therefore the eight had to be played. How would you rule, and would you try to apply the Law if you were East?"
1. Declarer could render his intention incontrovertible (and save a lot of pointless hassle) by complying with the law.
2. You (East) should call attention to the infraction (especially at teams).
3. After attention has been drawn to an infraction, you should call the director.
4. The director should rule in your favour.
5. Failing that the director might consider a procedural penalty for declarer
6. If the director rules in your favour, you might ask the director to waive his ruling, depending on circumstances.
7. (Ancipating a likely put-down), If you really want a life, consider another pastime
