The glyphs were changed between Unicode 2.0 and 3.0. They are now correct.
The reasons are stated in http://www.unicode.org/reports/tr25 (and also
tr28, I believe).
The source of the earlier arrangment comes from the practice of ISO to show
representative glyphs for the characters in 8859 and similar standards in
their sans-serif forms. The 'loopy' phi is apparently used very commonly
with serifed fonts, but equally commonly not used with sans-serifed fonts.
For Greek *text* that distinction is aesthetics only, but for mathematical
use of Greek symbols the distinction is crucial. For more information see
the reports cited.

PS: The printed version of earlier versions of the Standard are of
interested, but if there is a change, you must also consult all later
versions, or you will miss the rationale for the change.
