That information is also available in RDF, via the liblrdf library (or any
other RDF implementation of your choice):

    defs = lrdf_get_scale_values(plugin_id, port_number);
    for (i = 0; defs && i < defs->count; i++) {
        printf("%f = '%s'\n", defs->items[i].value, defs->items[i].label);
    }
    lrdf_free_setting_values(defs);

defs->items[i].value contains the value number (e.g. 1.0) and
defs->items[i].label contains the corresponding label (e.g. "AfterBurn (Long)")
