Why not just use a random number between 1 and 5?
You can use an Assertion to check the general format of the reply first if
required.
Or you can read the random value from a file using _StringFromFile() or
__CSVRead().
==
The regular expression extractor has a random function.
For this to be of any use, the regex must be able to match several times
when repeatedly applied to the target (the RE engine will move past the
start of the previous match and try again).
Your RE "anchors" the match to start with name="cbo_Type", which means it
cannot match again - unless that string appears again.
You could try just
(?s:<option\s+value="(\d+)"\s*>)
and see what happens.
If the value can contain non-digits, you'll need to change "(\d+)", but
beware of accidentally matching too much. This should work for all except
values with embedded double-quote:
"(.+?)"
i.e. match anything one or more times, but don't be greedy. Thus it will
stop when it matches the immediately following ", rather than continuing
until it finds the last possible ".
If there is more than one combo-box on the page, I suppose it would be
possible to use the regex *extractor* with anchored search to extract only
the relevant options, and then use the regex *function* on that to select a
random value.
I recommend trying these out in the Regex Tester - truly magical!

Subject: Re: Extracting Random Value from a Combobox
I don't think you can do that with regular expressions. To do so would
require the matcher attempt to match multiple different ways against the
same text, and that's just not how they work.
Alternatively, you can sometimes use the HTML Link Parser for this sort
of thing. I say 'sometimes' because it's a touchy piece of code that
likes things just so, but if your HTTP Request is otherwise
straightforward, you might be able to do so.
The basics of using it involve attaching an HTML Link Parser to the
request you want to modify (ie, not the previous request as you would do
with the regular expression post processor). Then, in your request you
have a parameter named "cbo_Type". For the value of that parameter, put
'*'.
It might be as easy as that. Or not :-)
