The 2nd with PASS/FAIL (this is determined by the "status" : 0 output for some tests and with a number between 1 and 4000 for others (i used regex for this, but I struggle a bit here too) and the 3rd one which returns the Value ( 0 in case status is 0 or the number between 1 and 4000 for the other tests).

 From what you've said above, your basic problem is that you need to 
parse the output looking for lines containing '"status": <n>' where <n> 
is some number.

Let's assume that you have run one of the shell scripts and captured its 
output into a string.  The first thing to do is to split the output into 
lines, which you can do with the "split()" string method.  Then check 
each line in turn.  If it contains a colon it may be what you want. 
"split()" the line at the colon and look at the first half.  Once you 
have "strip()"ed off the spaces at the beginning and the end, is it 
"status"?  If so, you've got your pass and the VALUE you want is in the 
second half.

I hope that helps.
