Apart from the addition of 'E' in the prefix, the Australian and British catalogue numbers tracked(pun not intended) each other fairly closely. I wonder if the US issue had the same catalogue number? Probably did!
Ah, just found the original 1979 issue of Sometimes You Win. Composer credits are missing here but can be seen by looking at the Fame reissue. And, sure enough the catalogue number is as I said it was, and survives as the matrix number for the Fame issue.
The only variants to the cover for the original issue are: on front, no Fame logo across top-right corner(oblique), and on rear, the English and Euro catalogue numbers at top-right, and at bottom-right(right of Capitol tm), EMI Records Ltd., Hayes Middlesex England.
