The Wikner I posted upthread mentions the tradition concisely in on
p.3/6 under (a)Rgveda:

http://www.evertype.com/standards/iso10646/pdf/vedic/Vedic_accents_doc.pdf

   (a) R.gveda has udattaa unmarked the svarita (jatya or suddha) is
   marked with a vertical line above the syllable (e.g. XX), but the
   kampa is indicated by a numeral 1 following the vowel if it is
   short, or the numeral 3 if it is long, and in both cases there is a
   vertical line above the numeral and a horizontal line below it in
   the case of the long kampa vowel the syllable usually also has a
   horizontal line below it (e.g. XX ).

The canonical work (this version not searchable unfortunately)
https://archive.org/detauls/vedicgrammar00macduoft/vedicgrammar00macduoft
- pdf p.468, p.450 talks about the accents 1 and 3 numerals used in
this way.

I've seen a number of pdfs introducing vedic accents in the wild that
document this. Maybe I'll try to make a bibliography
