Other comments: Desiya has a vigesimal numeral system similar to that of Kotia language. As a South Asian language an important numeral is for 100,000 (as in Indian English lakh): 100,000 lak or lokjo, rarely used is the numeral for 10,000,000 (an in Indian English crore): 10,000,000 koʈi.
Note: Desia and Adivasi Oriya are the same language, i.e. Glottolog: adiv1239 ISO 639-3 ort. Desia (or less frequently Desia Oriya) is the name used by most of its speakers (as far as I can tell) and it is the general name of that language in Odisha (formerly Orissa )  Adivasi Oriya is the name used mainly in Andhra Pradesh, but not necessarily by the speakers themselves, as not all of them are or identify as Adivasi (i.e. "tribal"). The names do not correspond to any coherent dialect (or sociolect) division.
Kotia Oriya was used by SIL people in the 70s, as they seem to have worked with
people from the Kotia community. Except for early publications of SIL, I haven't seen
it used for the language.
As for the differences between my list and the Adivasi Oriya list:
Vowel length has been reported to be contrastive for some varieties of Desia/Adivasi Oriya, but I have not found a variety for that this is true. It may be true for the varieties of the Araku Valley where the SIL people did most of their work in the 70s, but looking at the various materials from the Araku Valley, I doubt that it is.
I don't know of any claim that aspiration would be contrastive in any variety of Desia/Adivasi Oriya, so I suspect that the aspiration in the Adivasi Oriya list is non-phonemic. In all varieties I know, all unvoiced stops are aspirated and all voiced stops are not.
GoTek and duiTa are definite (or maybe specific) forms of the numerals ek and dui. There is no reason to list them only for one and two. You can add the affix or clitic -Ta to any numeral, e.g.  tinTa and pantsTa and dosTa are all correct and frequently used numerals.
manek for hundred has been reported for Desia/Adivasi Oriya, but it is a volume measure – one "man", a type of measuring container for grains and I have not been able to verify its use as a numeral. As far as I have seen it used, it is always used as a non-numerical quantifiers, similar to "lots of" or "a bunch". (It obviously contains the numeral one "ek", but that is the normal way of counting with quantifiers, manek, dui man, tin man, ...).
