This sort of range restriction is done in the policy script instead of
the permission.  You'd use something along the lines of:

// if the patron is in a "local-only" group...
if ( ( patronProfile.match("localHoldGroup1") ||
patronProfile.match("otherLocalHoldGroup") )
  // ... and their home library is not within the same system as where
the item lives ...
       && !hasCommonAncestor(whereAmI, patron.home_ou.id, 1) ) {
  // ... then disallow the hold
    result.events.push('ITEM_NOT_HOLDABLE');
}

in circ_permit_hold.js.  Because the target of the hold is a bib
record, and bib records don't have an owner (all shared everywhere),
there's no org unit to test the permissions against.  We don't use the
copies on the bib as a surrogate because there is much more to
holdability of a copy for a particular patron than those range-type
tests.

In trunk/1.6 we have an interface for building all the hold and circ
rules, including these per-group range tests, for use with the in-db
circ/hold logic, but until then, the scripts are the way to go for
this.

Does that help?

(Also, do note the issues that Jason raises later in this thread about
doubling the perms for subgroups. We believe that the issues with
those are now simple aesthetic, but it's best to avoid the issue.)
