Are you sure that that is the UNIcode code point of the numeral sign? To
me it appaears as an apostrophe. In any case is a strange situations.
Examine the hyphenation files for ancient greek; thay are prepared by
Apostolos Syropoulos, who is very knowledeable in this matter.
I am not even responsible for the LGR 8-bit greek fonts, even if I did a
lot of work on those particular hyphen files; I know that in the LGR
encoding the upper and the lower number sings are not treated as letters.

With "ancientgreek" selected, XeTeX hyphenates :
Τῆ Εʹ τῆς ΚΑʹ ἑβδο<supplied>μάδος
as
Τῆ Ε-ʹ τῆς ΚΑʹ ἑβδο<supplied>μάδος
i.e., between the Ε-majuscule and the number sign "ʹ".
It sounds like you have set up the numeral sign for hyphenation (i. e.,
given it a non-zero \lccode). Is that on purpose?
