People intend to donate the money when they win because they don’t want the prospect of gaining money to influence their decision. Donating it is just an alternative to burning it. (It does also follow that those people who donate it for this reason must find the utility of such a donation to be very small.)
By ‘their decision’ do you mean the decision to cooperate or defect? If so you would predict people would not offer to donate if there was no choice involved (e.g. all participants in the survey automatically receive one entry)?

It does not seem like this is what people are describing e.g. http://lesswrong.com/lw/j4y/2013_less_wrong_censussurvey/a3xl http://lesswrong.com/lw/j4y/2013_less_wrong_censussurvey/a2zz and http://lesswrong.com/lw/j4y/2013_less_wrong_censussurvey/a36h
