I am not sure about the relevance of the Meteg problem, but I do know
about a case, where different relative positions of the same
diacriticals are used for conveying a semantic distinction. In a big
reference work about verse metrics in the world's languages (Erika
Szepes - István Szerdahelyi: Verstan, published by Gondolat, Budapest,
1981), when discussing quantitative metrics, a macron above a breve is
used for denoting a neutral syllable of the metrical pattern that is
more frequently filled in by a short syllable than by a long one and
a breve above a macron is used for the reverse, i.e. the difference in
the combinations provides statistical information.
Actually, these signs are typically (although not inevitably) spacing
characters, but I don't think it makes a significant difference in this
perspective.
