Random Selection of Actions with Script. Possible?

You didn't write which app you were talking about.

This would be a guideline for Illustrator.

try {
  app.unloadAction("Random Action Set", "");
  app.loadAction(
    File($.__dirname + "/resources/actions/Random Action Set.aia")
  );
} catch (error) {
  app.loadAction(
    File($.__dirname + "/resources/actions/Random Action Set.aia")
  );
}
var randomActions = [
  "This",
  "That",
  "And",
  "The",
  "Other"
];
var action1, action2, l;
l = randomActions.length;
action1 = Math.round(Math.random()* (l-1));
action2 = action1;
while (action2 !== action1) {
  action2 = Math.round(Math.random() * (l - 1));
}
app.doScript(randomActions[action1], "Random Action Set", false);
app.doScript(randomActions[action2], "Random Action Set", false);
