It is because some of your bookmarks (most of them, as the count goes from 62 in the original, down to 16 after your sort) include the paragraph BEFORE the heading your sorting. That is the starting (opening) marker of the bookmark includes the previous paragraph. Here is the result of running the following code.
Code:
Sub BM_Count()
Dim SourceDoc As Document
Dim CountDoc As Document
Dim var
Code:
Set SourceDoc = Documents("Glossary Sorted.doc")
Set CountDoc = Documents("BMCount.doc")
For var = 1 To SourceDoc.Bookmarks.Count
CountDoc.Range.InsertAfter SourceDoc.Bookmarks(var).Name & vbCrLf
Next
End Sub
This simply listed the bookmarks names into a document so I could see them at a glance. The following shows the result of the original sort killing lots of bookmaks, and the result after I fixed a few paragraph marks.

So, for example the bookmark Binary Code is lost. So go there and look. Oh...make sure your have Bookmarks listed as Visible - They look like grey square brackets. As you can see the opening bracket of the bookmark Binary code includes the previous paragraph. And as you can see from the original sort, it is lost. If you simply delete the paragraph - just to the right of the opening bookmark...ummm, mark - and run the sort, it now IS still there.
I did a few just to test if this worked, and AFAIK, it does. I am not going to edit and fix your document for you. Just delete the paragraphs before the heading that is supposed to be in the bookmark.
NOTE! There are many instances where the bookmark closing mark (or tag if you will) includes a following paragraph (as opposed to a previous one). This does NOT affect the sort and the bookmarks. You can leave them if you want.
