It should, I think, be possible to use STL algorithms against
gsl_vectors if you are careful.  From the documentation [1], a
gsl_vector has size, stride, and data members.  If you create a
RandomAccessIterator [2] implementation that honors this information
and appropriate first and last iterator instances, you should be able
to use STL algorithms like std::sort [3].  I cannot speak to the
performance, but it should be reasonable.

The first (minor?) hurdle seems to be creating or finding a strided
iterator.  I'd love to hear what you find.
