Yes, sorry: I figured that I had answered the wrong question after I
sent it, but I was too tired to fix my mistake at that time. However, I
could not make your formulation work for me at all. I still don't
understand how it could possibly work: afaict, org-entry-get returns the
birthday as a string, "5 4 1900", the read returns the month as a
number, 5, and diary-anniversary should blow up because it needs at least two
arguments (a month and a day) - and it does in my case.

Be that as it may, re. filling in the name, I don't know how to do it
and I'm not sure that it can be done: the string after the function call
is scanned for %d but no other evaluation is done. org just passes the
string along and all of that work is done in diary-anniversary whose
doc string says:

| The diary entry can contain `%d' or `%d%s'; the %d will be replaced
| by the number of years since the MONTH, DAY, YEAR, and the %s will
| be replaced by the ordinal ending of that number (that is, `st',
| `nd', `rd' or `th', as appropriate).  The anniversary of February 29
| is considered to be March 1 in non-leap years.

So I think that's all you can do.
