This might depend on the precise wording used, but I wonder if it's a question of people not starting to listen properly until part way through the sentence?
Suppose option 2 says "You get $50 now, and also you can choose $300 in a week or $900 in a year", and option 3 says "You get $50 now and $300 in a week, or $50 now and $900 in a year". Someone who wasn't listening properly for the first four words of each would naturally treat option 2 exactly like option 1, but would treat option 3 very differently and might easily consider that money right now trumps money in a week in addition to the extra $600 a year later.
