There sample command to retrieve the latest version of the Container Security Operator and its channel does not get the latest version info.     

4.12 ~ 4.18    

Always    

    1.Go to https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/security_and_compliance/pod-vulnerability-scan#security-pod-scan-cso_pod-vulnerability-scan
    2.Check the command that "Retrieve the latest version of the Container Security Operator and its channel" in step 2
    

The sample command is,
$ oc get packagemanifests container-security-operator \
  -o jsonpath='{range .status.channels[*]}{@.currentCSV} {@.name}{"\n"}{end}' \
  | awk '{print "STARTING_CSV=" $1 " CHANNEL=" $2 }' \
  | sort -nr \
  | head -1    

Try the command without "head -1", 
$ oc get packagemanifests container-security-operator   -o jsonpath='{range .status.channels[*]}{@.currentCSV
} {@.name}{"\n"}{end}' | awk '{print "STARTING_CSV=" $1 " CHANNEL=" $2 }'   | sort -nr
STARTING_CSV=container-security-operator.v3.9.10 CHANNEL=stable-3.9
STARTING_CSV=container-security-operator.v3.8.15 CHANNEL=stable-3.8
STARTING_CSV=container-security-operator.v3.7.14 CHANNEL=stable-3.7
STARTING_CSV=container-security-operator.v3.6.10 CHANNEL=stable-3.6
STARTING_CSV=container-security-operator.v3.5.7 CHANNEL=quay-v3.5
STARTING_CSV=container-security-operator.v3.4.7 CHANNEL=quay-v3.4
STARTING_CSV=container-security-operator.v3.13.4 CHANNEL=stable-3.13
STARTING_CSV=container-security-operator.v3.12.8 CHANNEL=stable-3.12
STARTING_CSV=container-security-operator.v3.11.9 CHANNEL=stable-3.11
STARTING_CSV=container-security-operator.v3.10.9 CHANNEL=stable-3.10

Instead of using sort with numeric-sort (sort -n), we should sort it with version-sort (sort -V).

So the expected command should be,
$ oc get packagemanifests container-security-operator \ -o jsonpath='{range .status.channels[*]}{@.currentCSV} {@.name}{"\n"}{end}' \ | awk '{print "STARTING_CSV=" $1 " CHANNEL=" $2 }' \ | sort -Vr \ | head -1
