Not that I know of :).

This sounds reasonable, but I'm not brave enough to change
the order of the arguments (unless Karl gives the green
light :).  Can't you swap title and number arguments in a
call to \writetocentry?  Of course, you loose the nice
one-token expansion for the number which \writecontentsentry
does for you, but you still can do the expansion yourself
(using tricks with \the\toks and \edef).  And to avoid
expansion of the first token of the title (which now comes
in place of the number), just save the title in a token
register and pass \the\toks for the title?

I know this sounds like one ugly hack, but it should work.

Thanks for the ideas,
