Philippe has found a bug: the minutes of Mtg 103 make clear (103-C10) that the properties for Balinese characters were to be as specified in L2/05-090, and those have canonical decompositions for these multi-part vowels.
I've checked the UnicodeData.txt properties for Balinese, and the decomposition mappings are the only ones with errors. Here are the corrected entries for the affected characters:
1B06;BALINESE LETTER AKARA TEDUNG;Lo;0;L;1B05 1B35;;;;N;;aa;;;
1B08;BALINESE LETTER IKARA TEDUNG;Lo;0;L;1B07 1B35;;;;N;;ii;;;
1B0A;BALINESE LETTER UKARA TEDUNG;Lo;0;L;1B09 1B35;;;;N;;uu;;;
