    Create a function that organizes student performance data by sorting a collection of student ID and score pairs based on their achievement scores, enabling the learning platform to appropriately sequence content difficulty. The function should arrange these student-score pairs in ascending order based on the performance scores to facilitate adaptive content delivery. This sorting mechanism will help determine optimal learning paths for different student proficiency levels.
