My fault, because I didn' realize that numbers only appeared on each
fifth line.

Adapting from your code:
\startluacode
document.my_name_space = document.my_name_space or {}
document.my_name_space.pages = document.my_name_space.pages or {}
local f = io.open(file.addsuffix(tex.jobname,"tuc") )
print('>>>>> ',f)
if f==nil then
--[=[ do nothin ]=]
else
f:close()
local tuc = dofile(file.addsuffix(tex.jobname,"tuc"))
local data = tuc.structures.references.collected[""]
local w
local pages = document.my_name_space.pages
local realpage,ref
for k, v in pairs(data) do
w=string.gmatch(k,'LIN:(\%d+):\%d+')
ref = tonumber(w())
realpage = tostring(v.references.realpage)
pages[realpage]= pages[realpage] or {}
table.insert(pages[realpage],ref)
end
for page,array in pairs(pages) do
table.sort(array)
end
end
\stopluacode
\definemarking[linenumber]
\define\LinenumberCommand
{\normalexpanded{\setmarking[linenumber]{\linenumber}}\pagereference[LIN:\linenumber:\currentpage]}
\setuplinenumbering[command=\LinenumberCommand,step=5]
\startsetups linenumber
\startluacode
local l=0;
if document.my_name_space == nil then return end;
if document.my_name_space.pages == nil then return end;
local pages = document.my_name_space.pages;
for _,_ in pairs(pages) do l=l+1 end;
if l== 0 then return end;
--[=[ OK, we have some data to print ]=]
local array = pages[tostring(tex.count.realpageno)]
l=0;
if array ==nil then return end;
for _,_ in pairs(array) do l=l+1 end;
if l>0 then context(array[1].." -- "..array[l]) end;
\stopluacode
\stopsetups
\setupheadertexts[\texsetup{linenumber}]
\starttext
\dorecurse{6}{\input tufte\par}
\startlinenumbering
\dorecurse{20}{\input knuth\par}
\stoplinenumbering
\startlinenumbering
\dorecurse{20}{\input knuth\par}
\stoplinenumbering
\stoptext
On page 7 lines are numbered from lowest to highest values. A purist
might consider this wrong, but this is unlikely to happen on a real
book, since (I guess) line numbers on headers only make sense when they
two different series cannot be on the same page.
Many thanks for your help,
Pablo
