About the shown order of the loaded PK3, first ones are the one which may override the last ones content. As you can see sg_pak1.pk3 is shown before sg_pak0.pk3 and you're precisely loading the QVM from sg_pak1.pk3.
About sg_developer.pk3, there are only 2 files in it. This 2 files are completely new and then can't be overrided. Btw, here is a picture showing weapon debug if sg_developer.pk3 is missing... As you can see, default shader and texture are taken:
