That didn't work at all for me. I tried to number them in custom/blueprints/styles. Then you get duplicate styles in the admin panel from the custom folder and from admin/blueprints/styles folder. I can't delete the styles in the admin folder or they they will be added back on template update. I don't see how this can possibly work, unless I'm missing something. The order of the styles must be determined somewhere.

Ok, I put all the sections in /gantry/theme.yaml and this controlled the ordering perfectly. However, as you noted, the custom/gantry/theme.yaml does not override for some reason. This is contrary to what the documentation says at:
