Stats.min is incorrect for ordered sliding windows?

[tvcutsem]

Given the following code using a fresh checkout of the repository on node v0.10.26:

var windows = eep.EventWorld.make().windows();
var win = windows.sliding(eep.Stats.min, 3);
win = windows.ordered(win);

win.on('emit', function(value) {
  console.log('min:' + value);
});

var values = [1,2,3,4,5,6];
for (var i in values) {
  win.enqueue(values[i]);
}

I get:

min:1
min:1
min:2
min:3

While I would have expected:

min:1
min:2
min:3
min:4

Replacing Stats.min by Stats.max I get the expected behavior, so I suspect there's an issue with Stats.min.

Update: the problem also occurs with Stats.max, on a different sample. So the error is probably in the ordered window:

var windows = eep.EventWorld.make().windows();
var win = windows.sliding(eep.Stats.max, 3);
win = windows.ordered(win);

win.on('emit', function(value) {
  console.log('max:' + value);
});

var values = [1,2,3,2,1,0];
for (var i in values) {
  win.enqueue(values[i]);
}

Gives:

max:3
max:3
max:3
max:3

Expected:

max:3
max:3
max:3
max:2

It looks like i've broken this (again). Thanks for the testcase!
