SQL Re-sorting the result of a query

问题

Looking for some help, to re-order the result of a query.

So I have a table that contains just two columns ID, Tag.

Sample data:

1, France
2, Germany
3, Spain
4, USA
5, Spain
... and so on

I use a query to pull out the five most popular tags:

SELECT COUNT(ItemID) as tagcount, tag
FROM TagTable
GROUP BY Tag
ORDER BY tagcount DESC
LIMIT 0, 5

This works well and gives an output, for example:

49, France
47, USA
42, Italy
39, England
38, Portugal

However, after plucking the "top 5," I'd like the output to be alphabetical, eg:

39, England
49, France
42, Italy
38, Portugal
47, USA

Is this possible and if so, how?

Wrap it into one more select:

select * from (
    SELECT COUNT(ItemID) as tagcount, tag
    FROM TagTable
    GROUP BY Tag
    order by tagcount desc
    limit 0,5
) t1
order by tag
