The Altmetrics score is a weighted count showing the attention that an article has received. The score is calculated by volume (how many mentions the article has), sources (different sources have different values e.g. a news outlet is worth more than a tweet), and authors of mentions (who their audience is etc.)
This article has a high score partially due to being picked up by a large number of news outlets
