I am attaching the promised patch to org-exp.el. Can someone review and
commit this change?
Please note that I have withheld the changes to org-odt & co which make
use of this change.
ps: The patch to org.texi will follow soon - maybe in a day or two.

Subject: [PATCH] org-exp.el: Enhance `org-export-number-lines' to support odt export
* lisp/org-exp.el (org-export-number-lines): Modified. Add a
new parameter `preprocess' and use this for backend-agnostic
handling of literal examples.
This parameter is currently exercised only by the odt exporter. Hint:
See future commits.

+TEXT contains the source or example block.
+
+SKIP1 and SKIP2 are the number of lines that are to be skipped at

+backend-specific lines pre-pended or appended to the original
+source block.
+
+NUMBER is non-nil if the literal example specifies \"+n\" or
+\"-n\" switch. If NUMBER is non-nil add line numbers.
+
+CONT is non-nil if the literal example specifies \"+n\" switch.
+If CONT is nil, start numbering this block from 1. Otherwise
+continue numbering from the last numbered block.
+
+REPLACE-LABELS is dual-purpose.
+1. It controls the retention of labels in the exported block.
+2. It specifies in what manner the links (or references) to a
+ labelled line be formatted.
+
+REPLACE-LABELS is the symbol `keep' if the literal example
+specifies \"-k\" option, is numeric if the literal example
+specifies \"-r\" option and is nil otherwise.
+
+Handle REPLACE-LABELS as below:
+- If nil, retain labels in the exported block and use
+ user-provided labels for referencing the labelled lines.
+- If it is a number, remove labels in the exported block and use
+ one of line numbers or labels for referencing labelled lines based
+ on NUMBER option.
+- If it is a keep, retain labels in the exported block and use
+ one of line numbers or labels for referencing labelled lines
+ based on NUMBER option.
+
+LABEL-FORMAT is the value of \"-l\" switch associated with
+literal example. See `org-coderef-label-format'.
+
+PREPROCESS is intended for backend-agnostic handling of source
+block numbering. When non-nil do the following:
+- do not number the lines
+- always strip the labels from exported block
+- do not make the labelled line a target of an incoming link.
+ Instead mark the labelled line with `org-coderef' property and
+ store the label in it."
