Given a class, what reasoning is there for either of the two following code styles?

Style A:
class Foo {
    private:
        doWork();

        int bar;
}

Style B:
class Foo {
    private:
        int bar;

        doWork();
}

For me, they are a tie. I like Style A because the member variables feel more fine-grained, and thus would appear past the more general member functions. However, I also like Style B, because the member variables seem to determine, in a OOP-style way, what the class is representing.

Are there other things worth considering when choosing between these two styles?
