Tyrrell's case garnered the endorsement of celebrities such as "Hunger Games" star Josh Hutcherson and Jesse Tyler Ferguson from television's "Modern Family" and Max Adler and Dianna Agron from "Glee."
Tyrrell, a hardware store salesperson, and her family were honored at the GLAAD Media Awards earlier this year in Los Angeles for taking a stand.
Just two months ago, the Boy Scouts acknowledged their policy was controversial, but said in a statement to the media, "To disagree does not mean to disrespect and we respect everyone's right to have and express a different opinion. Scouting will continue to teach our members to treat everyone with courtesy and respect."
The organization also said that in Tyrrell's case the policy had not been followed by local leaders, but when another pack leader complained, it was enforced.
Wahls became a national figure after he spoke at a public forum on House Joint Resolution 6 in the Iowa House of Representatives last year.
He dropped out of the University of Iowa last year to do advocacy work and is the author of "My Two Moms: Lessons in Love, Strength and What Makes a Family."
His online video of the impassioned speech went viral last year.
"Zach and the thousands of scouts and scout leaders who have joined Jennifer's campaign were able to connect through the petition in a way that has never happened before, which definitely caught the attention of the Boy Scouts of America," said Mark Anthony Dingbaum, Campaign Manager at Change.org.
Change.org has been instrumental in other campaigns, most notably the Trayvon Martin case, which also caught the nation's attention and resulted in the arrest of George Zimmerman for the fatal shooting of the 14-year-old.
