Hi, I want to sort a tuple consisting of two floats and one array by the absolute value of the first float in reverse order. What I did is the following:

```
from numpy import *
test = [(-0.02, 100.2, array([1, 0, 0])),
(-4.02, 300.4, array([1, 1, 0])),
(3.57, 503.7, array([1, 0, 1])),
(0.01, 700.0, array([0, 0, 0]))]
for f in range(len(test)):
sorted(test[f], key=lambda item: abs(item[0]), reverse=True)
TypeError: 'float' object is unsubscriptable
```

Any ideas?
