What do you mean, "reverse the word order"? The point is that
"Hertford County" is completely unidiomatic even in British usage,
precisely because the word order is wrong.

Usages would be

Hertfordshire
County of Hertford (obsolete pre-1974 legal usage)

It is still in current use, e.g. in S.I.2009/776 [HIGHWAYS, ENGLAND
The Watford and South of St Albans—Redbourn—Kidney Wood, Luton,
Special Road Scheme 1957 (Variation) Scheme 2009]
THE SCHEDULE
The Route of the Special Road
From a point on the London-Aylesbury-Warwick-Birmingham Trunk Road
(A.41) near Watford in the County of Hertford.......

County of Hertfordshire (modern legal usage)

All that the Irish do is drop the "of", like we do with Durham. (And
even then, "County of Durham" can be found in acts of Parliament)

Even "Hertfordshire County" is more idiomatic than "Hertford County",
which has never been proper usage in Britain in either of our
lifetimes.
