Replying to myself. In in the second "If failed", I used port 82, which 
was a typo but, it does not a difference. I read through the documents 
again and it appears impossible to do what we need. Since we cannot send 
an alert on {exec,alert} and have no way to selectively alert, I thought 
I would simply add a solution that may be included in the future.

All we need in the above is to have a additional parameter which will 
only alert when the check fails 10 times.

Change this:

If if failed host localhost port 81 send "POST $some_txt" expect 
"$some_txt" then exec "$a_script"

To this:
If if failed host localhost port 81 send "POST $some_txt" expect 
"$some_txt" then exec "$a_script" AND alert if failed $NUM times within 
$NUM cycles with reminder on $NUM cycles.

Problem solved and I think logical to boot.
