Opinions on include order and coding standards

Hi All,

Just wondering if people have any opinions on how include's should be
ordered.  Personally I use style A. Are there any practical reason for
either style. I assume both would have about the same compile time, so
no savings there.

Style A
#include <c++, system headers>
#include <library headers>
#include "local headers"

Style B
#include "local headers"
#include <library headers>
#include <c++, system headers>

Also what should be the goals of, or included in, a c++ coding
standard. I think they should be, (not in any order)
1. Standard and ****table behavior
2. Readability of code
3. Best practices

As you may have guessed we are changing our internal coding standards.
