Sorting 对地图切片排序

我有一个10张地图的切片，如何按其中一个值排序

[{"name":"a","score":100},
{"name":"z","score":150},
{"name":"s","score":120},
{"name":"x","score":110},
{"name":"r","score":10},
{"name":"b","score":1300},
{"name":"b","score":1500},
{"name":"w","score":1002},
{"name":"o","score":140},
{"name":"q","score":101}]

我想用

score

值按降序对切片进行排序，但我不知道如何排序

只是一个简单的

排序.Slice

sort.Slice(information, 
func(i, j int) bool { 
    return information[i].Difference > information[j].Difference 
})

映射的类型是什么，

map[string]接口{}

？或者它们是结构化的？最简单的方法是，它甚至附带了一个示例。
