What did you export to (I mean, what program or service?). I tried that but FF wouldn't let me import it. Also tried CSV. So I've been having trouble finding a program/service that will read either RSS or CSV.
On 2010-07-10 I exported as usual to RSS format, on 2010-07-27 I exported to Delicious format, on 2010-07-27 I exported to Netscape format.
All three exports do include tags.
In the Netscape Bookmark format, tags appear in this format —
SHORTCUTURL="tag tag2 tag3"
The import to Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-GB; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 took some time (I had to ask Firefox to continue with an unresponsive script) (Diigo counts 9.069 bookmarks, Firefox counts 9,068). It recognised the names and locations, but not the tags.

It may be that more modern versions of Firefox:
* can not use tags in the HTML format provided by Diigo export
* must use JSON format to import tags.
