Sounded similar although I thought this was originally from Joey Hess.

I suppose, it's not really "ignore the first couple of characters", as
they may matter if you order the lines differently, isn't it? Else your
perl script could simply leave out putting those numbers into the buffer
in the first place and just add them after the file has been written
when you actually need them.

I don't think there are good alternatives. You can conceal the first
couple of characters, but that won't help against users changing those
unexpectedly.

I have written the NrrwRgn plugin, that might be an alternative. It can
open a selected region inside another window and on ':w' will write the
changes back into the original buffer. That won't help against ordering
the lines differently.

Best,
Christian
