Thank you. There is one major difference. In your language.dat there is just
    ukenglish ukhyphen.tex
without any additional synonym, while in a recent TeX Live there are
two additional synonyms:
    ukenglish loadhyph-en-gb.tex
    =british
    =UKenglish

Taking a look at the latest version of babel (but I doubt anything has
changed in the meantime):

\ifx\l at english\@undefined
  \ifx\l at UKenglish\@undefined
    \ifx\l at british\@undefined
      \ifx\l at american\@undefined
        \ifx\l at USenglish\@undefined
          \ifx\l at canadian\@undefined
            \ifx\l at australian\@undefined
              \ifx\l at newzealand\@undefined

it seems that only "UKenglish" and "british" are recognized keywords,
while "ukenglish" is not.

There is one more thing that you can try: add "=UKenglish" to you
language.dat below ukenglish line, and possibly the following to
language.def:
    \addlanguage{UKenglish}{loadhyph-en-gb.tex}{}{2}{3}

Then regenerate the formats ("sudo fmtutil-sys --byfmt pdflatex" or
"fmtutil --byfmt pdflatex", just in case check that "kpsewhich
pdflatex.fmt" returns the right one) and try again.

I'm almost sure that the difference comes from missing British, and as
Karl noted, American patters are used as a consequence.

Now I remembered that additional languages have been added to
language.def in 2008 (possibly later), so either the language was not
defined at all, or it was defined with a different capitalization.
