In the first IF block, if none of the conditions is true, local.list is undefined... maybe add an "else return 0"?

In the first FOR loop, will TAG.max_coowners TAG.max_friends or TAG.max_accesss (yes your script does add an extra "s") ever be zero? If so, your FOR loop goes from 1 to zero with possibly strange side effects... Maybe test whether those TAGs are zero and return 0 before the FOR loop starts? Also, your "inner IF statement" inside the first FOR loop references a LOCAL.lists varibale that doesn't exist.

If I were you I would abandon this TAG based data structure and use an actual LIST structure:

//- Added: Basic LIST support.
// LIST.xxx to show elements in list. Also, can be used like LIST.xxx=value to clear list and add a value
// LIST.xxx.ADD to add new element to list, can be number or string
// LIST.xxx.CLEAR to clear list
// LIST.xxx.index to read/write value on element in list
// LIST.xxx.COUNT to get count of elements in list
// LIST.xxx.index.REMOVE to remove element at specified index in list
// LIST.xxx.index.INSERT to insert element at specified index in list
// LIST.xxx.FINDELEM search_value returns index of first found element in list. Search starting from begin
// LIST.xxx.index.FINDELEM search_value returns index of first found element in list. Search starting from index
// SERV.PRINTLISTS to print all lists and their elements
// SERV.CLEARLISTS to clear all lists. If used with mask parameter, then clear all lists, which name countains specified mask
