BCDEGPTVZ FLMNSX AJK QUW IY H O R

[ Editor: posed by Peter H. Ten Eyck. ]

The letters in each group are pronounced with the same vowel sound (and
as I'm not a linguist, my descriptions of the vowels are necessarily
rudimentary):

BCDEGPTVZ        long e
FLMNSX                short e
AJK                long a
QUW                y-long u combination
IY                long i
H
O
R

If that's the answer, then I think H belongs with A, J, and K.

[ Editor: Matthew Daly <mwdaly@kodak.com> sent the archive the
  arrangement AHJK BCDEGPTVZ FLMNSX IY O QUW R, with this note: ]

The first is arranged by the vowel sound in the pronunciation of the
letter.  I've ignored the two extra schwas in W, which seems reasonable
since there are no other schwas in the other letters.
