I have a question about MS SQL Servers SCOPE_IDENTITY  -   this is the explanation MSDN gives:

SCOPE_IDENTITY returns the last identity value generated for any table in the current session and the current scope.

Can someone provide a brief explanation on what current session and current scope means?

I just want to be **guaranteed** that I will get the right value if I say:

SqlCommand comm ....

comm.CommandText = "INSERT INTO ..... ; SELECT SCOPE_IDENTITY()"
......

even if there are other connections to this DB going on in other currently running applications.

If you have multiple applications (or instance or thread) which are inserting data into your server then you should use Scope Identity. If you just use identity then it may pick up the last identity value inserted into the database. However scope identity will return the last identity value generated by your session so it will be guarented to return you the last one you inserted.
