I think a loop with a random function would suffice, but I don't think that there's any hard coded way to tell whether or not a midi is already playing, so you'd have to use specific wait commands equal to the approximate length of the midi. Here's some sample code, but the hard part is getting the wait commands to match up with the midi length.

void main ()
{
script_attach(1000);
int &rand;

loop:
&rand = random(3,1);

if (&rand == 1)
{
playmidi("1.mid");
wait(X);
}

if (&rand == 2)
{
playmidi("2.mid");
wait(X);
}

if (&rand == 3)
{
playmidi("3.mid");
wait(X);
}

goto loop;
}
