Number contents of "Adoru"

I'm starting to try to get a spreadsheet going for Adoru: Ekumena diserva libro, the 2001 Esperanto hymnal jointly published by IKUE and KELI, the leading international organizations of Catholic and Protestant Esperantists respectively. This is, as the title suggests, properly a service book and not just a hymnal, though it contains hundreds of hymns.

The Wiki says "Hymnary.org's practice has been to index everything in a hymnal that has a hymn number -- hymns, doxologies, musical responses, readings, etc." but while this sounds straightforward, it seems to assume that "a hymn number" is a whole number. In Adoru, however, a fair number of items have what amount to decimal numbers. While most of these are not hymns, some are. For example, on p. 907 the first item is numbered
531
("Estro de l' vivo, atentu pri mi." - a translation of the German "Herr meines Lebens" to be sung to SLANE), and the second item is numbered
531
     4
("Min lasu ĉe Vi resti." - a translation of the German "Laß mich dein sein und bleiben" to be sung to VALET WILL ICH DIR GEBEN [= ST. THEODULPH])

How should these numbers be handled? Will the Hymnary's software accept 531.4 as a hymn number?

I've put a tentative spreadsheet (about 50 rows of data) here, in Google docs so you can see what I'm talking about. The yellow-highlighted rows are the only ones that are actually hymns. This spreadsheet covers the first 42 pages of the book. Starting about p. 427, the hymnic content becomes much closer to 100% of the total content, and this continues for the most part through p. 1376.
