With the 4.8, I was using class->set("anglelabelitem","OGR:LabelAngle"), because angles are embedded in the layer. So now, as anglelabelitem doesn't exist anymore, I'm trying to use class->label->set("angle","OGR:LabelAngle") but it gives me no result. It doesn't produce errors but label aren't oriented.

In 5.0 we added the concept of attribute binding for some label and 
style properties, and that includes the label angle. See:
http://trac.osgeo.org/mapserver/browser/branches/branch-5-0/mapserver/MIGRATION_GUIDE.TXT

In PHP MapScript you should be able to use:

   $label->setBinding(MS_LABEL_BINDING_ANGLE, "OGR:LabelAngle");
