ybba, I just had my visa approved last September 2, 2011 and they looked at my english exam result so, I don't think it will be a problem, but just to make sure try phoning them, and ask. But before I took the exam last August, it was in the list that is why Itook the exam since we were running out of time and ielts says I can get the result by 15 days.
Goodluck!
