No, we presented this feature at the AOSD, but it was not integrated 
into 0.7.

Meanwhile this feature was integrated with a slightly different syntax, 
which is more flexible:

advice pointcut-expr : order ( high, ...low )

high and low are not names of aspects anymore but pointcut expression, 
which describe sets of aspects, e.g. order("A1","A2"||"A3",last()). This 
means that you don't need a forward declaration of the aspect names 
anymore and you can use arbitrary pointcut functions, match expressions, 
and named pointcuts.

We furthermore spent a lot of time to describe the advice ordering in 
the Language Reference Manual and made sure that the implementation 
really reflects this concept.

All this will be available in the next ac++ release.

Yours,

Olaf
