Yes, it does look unlikely. I don't know about the other comments (line
numbers, etc.) but at least the link calculation in
org-babel-tangle-collect-blocks is wrong I believe: it uses
org-store-link to supposedly store a link to the current location on the
global org-stored-links stack and then pops it, takes the car of it and
sanitizes text properties of the result: that then becomes the link that
should be stored in the tangled file.
But it seems that org-store-link does not behave this way when called
non-interactively: I get nothing on the global stack. Instead it seems
to *return* the link as a string, which is then just thrown away.
One can argue that org-store-link is wrong to behave this way[fn:1]
but I will let Eric and Carsten fight it out :-)

Footnotes:
[fn:1] assuming that it *does* behave this way and I am not fooling
myself.
