name of the japanese script

There's a sorting example in the editor's draft of SPARQL Query
  http://www.w3.org/2001/sw/DataAccess/rq23/rq25#modOrderBy
RDF Term				  Reason
					  Unbound results sort earliest.
_:z					  Blank nodes follow unbound.
_:a					  There is no relative ordering of blank
					    nodes.
<http://script.example/Latin>		  IRIs follow blank nodes.
<http://script.example/Кириллица>	  The character in the 23rd position,
					    "К", has a unicode codepoint 0x41A,
					    which is higher than 0x4C ("L").
<http://script.example/日本語>		  The character in the 23rd position,
					    "æ—¥",has a unicode codepoint 0x65E5,
					    which is higher than 0x41A ("К").
"http://script.example/Latin"		  Simple literals follow IRIs.
"http://script.example/Latin"^^xsd:string xsd:strings follow simple literals.

which is meant to illustrate codepoint ordering of IRIs. I don't
believe 日本語 identifies a script. Should I use 漢字 (0x6F22) instead?
Is Кириллица correct? Would something from Byzantine Musical
Symbols speak to a wider audience?
