This has come up before, it might be helpful to dig up the old references. The reason there is not a simple [random[]] operator is that filter operators are supposed to be deterministic: they must return the same results for the same inputs, regardless of when they are called. This property is required for the refresh mechanism to operate correctly. In particular, using a non-deterministic filter with the list widget will cause thrashing on every refresh cycle. To make it work, one needs to add a seed operand, and initialise that value via a new action widget that can assign a random value to a tiddler. I think somebody made a plugin a few years ago to do this.
