Unfortunately, the Quran does make some quite specific statements about science.
Some are the understanding of the day, some of which originated elsewhere, such as with the Greeks (you got quite irrational last time I mentioned that, even though it's very easily checked) and others are simply wrong, such as, for example, the claim that sperm originates between the ribs, a claim that we know is egregiously wrong, but which was the accepted wisdom of the age.
Thus is the Quran revealed as a collection of folk myths, history and primitive morality tales. Interesting as a historical document and indeed containing much truth, particularly concerning the early history of the faith, but fundamentally not a document that can possibly be considered inerrant by any stretch of the imagination.
Birdie's 4 point characterisation seems spot on to me.
