No.

$ ldapsearch -xLLL -h ldap.uio.no -b ou=people,dc=uio,dc=no "(uid=hbf)" sn cn
dn: uid=hbf,ou=people,dc=uio,dc=no
cn: Hallvard B Furuseth
sn: Furuseth

$ ldapsearch -xLLL -h ldap.uio.no -b ou=people,dc=uio,dc=no "(uid=hbf)" cn sn
dn: uid=hbf,ou=people,dc=uio,dc=no
cn: Hallvard B Furuseth
sn: Furuseth

What I meant about same order is that two calls to e.g.
ldap_get_values() with the same arguments might in theory return the
values in different order.  OpenLDAP preserves the order in that case.
