Based on the script styles, I would say the annotations on You are not allowed to view links. Register or Login to view. and You are not allowed to view links.

The annotations between the legs of the zodiac figures are probably added a little later, maybe 1420 to 1530.
The quire numbers are in a style that was popular between about 1390 to about 1480. Most writers had stopped using the old style numbers by about 1480, but there were still a few who used them into the early 16th century.
The foliation is in a style (and ink) that was common between about 1430 and 1590 or so. This style (and ink) was pretty common in the 1500s. Around the late 1500s, writing implements improved and people started using different kinds of pens and modern numbers became more common. By the 1600s, foliation didn't quite look like VMS foliation any more. Most people were using the new pens and the modern shape of 5.
.
I have hundreds of samples of medieval numbers that are relatively similar to the VMS foliation. The six closest samples range in date from about 1480 to about 1550. There are two that are slightly less similar that might be as late as 1600. It's hard to establish an exact date because they are rarely added at the same time the manuscript is made, but I have located palaeographic comparison samples within manuscripts that help establish a relative date for the style.
