Sort JSON_OBJECT?

With the new JSON functions, does anyone know if you can sort the results?

Here's an example query using an IBM sample table. It seems to give the correct results, but I need to be able to sort them.

select json_arrayagg(
json_object('CustNo' :CUSNUM,
'LastName' :LSTNAM,
'Initials' :INIT,
'Street' :STREET,
'City' :CITY,
'State' :STATE,
'Zip' :ZIPCOD,
'CreditLimit' :CDTLMT,
'ChargeCode' :CHGCOD,
'Balance' :BALDUE,
'Credit' :CDTDUE)
)
from QIWS.QCUSTCDT
where BALDUE > 0
