how common it is that electrostatic interactions are involved in

It's impossible to answer your question unless you define what you mean
by "degree of commonality".
If you are asking if salt bridges happen - yes, they do. All the time.
On the other hand, it must be impossible to conclude anything with
certainty about details of interactions within "intrinsically disordered
proteins". It's impossible to determine their structure because they
are, well, disordered. But I know of no law of physics that would
prevent electrostatic interactions in such molecules.
