I think you can simply do this:

(if (featurep 'fontset)
    (set-fontset-font "fontset-default"
		      (cons (decode-char 'ucs #x0D00)
			    (decode-char 'ucs #x0D7f))
		      (cons "misc-malayalam" "iso10646-1")))

There are fonts that have malayalam glyphs other than
"misc-malayalam", e.g. the font distribute here.
	http://openlab.jp/efont/dist/unicode-bdf/
They don't have "misc-malayalam" name but can be used in
Emacs as well.

So, even if Emacs finds "misc-malayalam" font, it doesn't
mean a user want to use it.

The problem of "iso10646-1" fonts is that, inspite of that
registy name, they don't contain the whole glyphs for
iso10646.  To select a proper font for for a specific
character automatically, Emacs has to check contents of each
font.  The current Emacs doesn't have this facility.  As I
implemented it for emacs-unicode, I'd like to ask people to
wait for emacs-unicode.
