While it's not quite highlighting them, you can mark the lines
somehow. I like to indent them, but you can also prepend/append some
other information to the line.

:g/\d\+/if getline('.')+0 > getline(line('.')+1)+0 | sil! > | endif

For this example, the whole line is just the number. You'd have to
tweak the getline(...) by wrapping it in something that extracts just
the number from whatever format of string your lines contain.

The "sil! >" is what indents the lines in question. Feel free to
modify as you see fit.
