Attached you will find the link to the .dsc file http://mentors.debian.net/debian/pool/main/p/python-scipy/python-scipy_0.12.0-2~bpo70+1.dscplease review and upload it to wheezy-backports repository, because the 0.10 version is from 2011 and extremely outdated. Furthermore the 0.12 version has no release critical bug reports.
thanks! best regards Roman Stingler
