The document that the data comes from (http://www.coachwei.com/blog/_archives/2008/1/22/3480119.html) has a comment at the end saying what versions were tested:
Browser versions used in this test:
IE 7.0.5730.11
FireFox 2.0.0.11
Safari 3.0.2 (522.13.1)
According to http://www.codedread.com/svg-support.php SVG 1.1 support of Firefox3 is 60%. Safari scores a bit higher, Opera much higher.

The main reason we're not scoring higher on SVG 1.1 is we lack support for SVG fonts --- and that's definitely on the roadmap. Apart from that, SVG 1.1 is very nearly done.
