Role Scoper has been translated into Spanish!  This translation applies to the Role Scoper Options form and all Restriction and Role setting interfaces.  Just extract the scoper.po and scoper.mo files into your plugins/role-scoper/languages folder.  Those files will be bundled in the next Role Scoper release.

Thanks to Rafael Pérez Gana of Rafo® Computación & Web for volunteering this work.
