The port number itself is not more or less secure than any other number.
You need to look at the service listening, if it is a web server then
which one? Once you know what you are dealing with it is simpler to
learn how vulnerable you will be.
Is the traffic encrypted? By what means? What client will be connecting?
The "scenario" you are mentioning does not specify anything but opening
port 3270 to a web server. This port number could be anything, think of
it as completely randomly picked. (just for the sake of getting the
question away from the port number itself).
This alone does not give you any information to answer if the traffic
can be sniffed...

Well, Management is asking whether, in this scenario; How secure will
be the traffic? They are asking the probability of data being sniffed.
The problem is that i do not have much info regarding the application.

Recently I got a change request which is to be implemented on the
firewall. The requirement is to allow port 3270 from inside network to
a webserver located in the outside world.
I would like to know the Risk/Threats associated with this change. I
dont know what kind of a data would traverse in this setup but most
likely its going to be something related with financial transactions.
Thanx & Regards
