Hello steve,

Use option '-p process-id' cannot search out the log which contains the given process-id and message type is AVC.

For example:
# echo 'type=AVC msg=audit(1221036190.313:3232615): avc:  denied  { append } for  pid=8961 comm="cupsd" path="/var/log/cups/access_log" dev=hda7 ino=1210126 scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:file_t:s0 tclass=file' | ausearch -p 8961
<no matches>
