This is not a bug: <C-o> executes one normal mode command and it is «zz» from
the mapping. What does LineNums function do? Maybe this code can be rewritten as

function s:WrapLineNums()
call LineNums()
return "zz"
endfunction
nnoremap <expr> zz <SID>WrapLineNums()
(Note that it changes the order of operation: LineNums appear before «zz»).

Another suggestion:

function s:WrapLineNums()
normal! zz
call LineNums()
nnoremap
nnoremap zz :call <SID>WrapLineNums()<CR>
