If you mark a control critical the server has to return an error code
if it does not support the control.
If you mark the control noncritical the server is allowed to ignore 
the request for the control and to act as if it was not requested.

To me your results indicate that the LDAP server you use does not support
have the Server Side Sort Control 
(AFAIK OpenLDAP 2.1.x doesn't. You can always check by searching the
rootDSE of the server for the list of supported controls and see if the OID of
the Server Side Sort is among the results)

You need to do the sorting manually on the client side.

No, changing the JLDAP implementation won't change anything. If the
server does not support the Server Side Sort Control then JLDAP 
cannot enfoce it.
