Well... There is no documentation of these tags in the OSM wiki.

ael mentioned that these are well-known terms. I tried several 
translators and dictionaries but didn't find anything.
A Google search only finds the wiki "List of mountains and hills
on the British islands", but not much more related information.

These seem to be very local terms that are not used outside of Scotland 
(British Isles?). In general we oppose such local terms as keys because 
they won't be of any use outside a small area.

Looking at the tag history, most of these were added in a few larger 
edits in 2014 and 2015.

What information do these terms contain exactly? What I understand from 
the Wiki page, the names are determined by three properties: The 
location (to be found from boundary relations), the height (tagged as 
'ele') and the prominence (tagged as 'prominence').

My very personal conclusion / opinion: These tags are undiscussed, 
undocumented, not well-understood outside a small area and useless 
because they can be derived from a few documented, verifiable tags.
