Not for ACK's, or more accurately, as you suspected, not for any packet where
the segment length is zero. From packet-tcp.c:tcp_analyze_sequence_number(),
starting at line 953:
if( seglen>0
&& tcpd->fwd->nextseq
&& (LT_SEQ(seq, tcpd->fwd->nextseq)) ){
...
/* out of order determination code */
...
}
