I attached the latest version, 0.3.8, to the first post. This version adds cursor positioning support, which was introduced in Sigil 0.9.7.

I.e., if you click an error message with a column number, it'll move the cursor to the indicated column number.

Note that the column numbers that epubcheck reports often point to the closing tag of tags with invalid or missing attributes. I.e. they might not be that helpful in tracking down errors.
