I assume that South's explanation of the 2♠ was really misinformation, and the agreement was it meant something artificial not showing anything about ♠ (maybe a relay), and East got the correct information. Maybe the OP can alert me if I am wrong.
Was West's double really a bad call? Maybe look at it from a different point of view: N/S bid a game, and not a slam. I do not see any evidence in the bidding that they even tried for a slam. Not bidding a slam means that they expect E/W to make 2 or 3 tricks. However, they did bid under the assumption that the ♥ will behave, and could not foresee a 5-0 break. West's ♥ suit are 2 extra tricks. The 5-0 break does not make it less likely that they get the 2 or 3 tricks that they should get anyway. Therefore, without looking at other evidence, West can expect the 4♥ contract to go down 1 or 2.
A little uncertainty is, however, the question if the ♣K will make a trick or not. Maybe, if there is a finesse for this K, and Partner has only one defensive trick, 4♥ can still be made. Therefore, West is interested to know which opp has the clubs, because the ♣A is more likely to be where most of the clubs are. If North has 4 ♠ cards, his likely distribution is 4=2=4=3 or 4=2=5=2, and it is quite likely that ♣K makes a trick. But if 2♠ is a relay and West knows nothing about the black suits, a defensive trick with the ♣K is significantly less likely.
Another point is East's double over 2♠. If West knew that 2♠ was artificial, he would also know that his partner has spade honors as the double was probably lead-directing. For a double West would like East's honors rather be in some other suit, maybe ♦, where the likelihood that they succeed in making tricks is higher.
Conclusion: West has good reasons to base her decision on whether to double or not on the information that 2♠ was natural, and the double was neither wild nor gambling, not even close. It is irrelevant how West reasoned for her double, because a bad reasoning does not turn a sensible call to wild and gambling. Besides, I suspect that the OP did not do a great job when presenting her reasoning.
The fact that she asked a second time if the 2♠ bid was really natural is strong evidence that she was going to base her decision on this information, whatever her true reasons were.
This means, the offending side got a better score by the misinformation, and this is all what Law 21B3 requires. And as I pointed out above, the double was not wild or gambling, so this is not a case of Law 12C1b.
Addressing bluejack's question if, assuming the double was wild or gambling, at least N/S should get the score without the double: I would say yes, because I would still believe that the misinformation made a difference for West when deciding about the double.
