When you add a message to a [qlist] or [textfile], it will always be appended to the end of the queue.

In the object that I need to implement, I need to be able, at any time, to schedule (i.e. add to the queue) a message whose time (the time at which it will be output) may be "earlier" than the time of messages already present in the queue.

You could do that with the "textfile" and "pipe" solution as well. The order of lines in textfile doesn't matter, if you pipe them to "pipe". If the pipe is already running, you may need to keep track of the time that has passed since then and adjust your start time accordingly. The only problem is that you need to initialize your "pipe" with arguments specifying the contents of your event messages. And I don't know if the number of messages you can store in a "pipe" is limited or big enough for you.
