Looks like a bug to me. The code to evaluate the "%!" is in
there but the option processing rejects the statusline with a
bang(!) in it.
This is probably not the best patch to the source, but it allows
the statusline string to make it through the option check:
--- src/option.h.00 2006-04-24 06:20:49.000000000 -0700
+++ src/option.h 2006-06-14 07:46:06.845082413 -0700

Alternatively, if your status line function is returning a string and
not another status line to be evaluated, you could use:
:set statusline=%{MyStatusLine()}
