Here are some visual examples. It's probably easier to explain it this way...
In the first two, the scribe used a conventional Latin apostrophe (in Latin this usually stands for a missing "m" or "n"). In the second two there's an extra line between the 4 and the o.
When Wladimir posted the examples, it made me wonder whether those extra lines between the 4 and the o meant something different from the overlines or... if maybe the scribe was looking for a way to add the line without it being so obvious (putting it between the letters instead of above it, so it is less likely to be noticed):
