As far as I know, Malayalam should work much as Devanagari does. The virama
inhibits the vowel, and a following ZWJ or another consonant will cause it to
take half-consonant form.
But in cases where you have Consonant+Virama+Consonant, *before* selecting the
half-consonant form, the rendering code is responsible for determining if this
pair (or group in some cases) of consonants should be combined to form a
vertical conjunct or ligature.
There is no "standard" way of determining which glyph to use. It is entirely
dependent on what glyphs are available in the font and how much the rendering
code knows about the glyphs in the font.
