Hi Benedetto,
with Mathematica version 5.1 without  "ConversionOptions" it seems to work:

fo = {{"aa", 1, 1., "ab"}, {"ba", 2, 2., "bb"}};
Export["Test", fo, "CSV"];
in = Import["Test", "CSV"] // FullForm

List[List["aa", 1, 1.`, "ab"], List["ba", 2, 2.`, "bb"]]

What is the ConversionOptions for?? With it you get the wrong answer

List[List["aa", 1, 1.`, "ab"], List["ba,2,2.,bb"]]
