You can use an item class with id in the vertices and set the id using 
the lexicographic order.

See for example this one:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/BGL_ref/Class_Polyhedron_items_with_id_3.html

typedef CGAL::Polyhedron_3<Kernel,CGAL::Polyhedron_items_with_id_3> 
Polyhedron;

Polyhedron::Vertex_handle vh=...;
vh->id()=4;
