What does grep have to do with this?
And what do you mean by min to max with relation to 'last 3'?
Here's a simple was to get the sorted last 3:
sort -un filename | tail -3
Here's a simple was to get the min and max:
sort -un filename | head -1 ; sort -un filename | tail -1
FYI: The u switch produces unique output, while the n switch sorts numerically (i.e. so 234 comes before 1234).

Intersting:
For curiosity, I changed one of the 432 values in the middle to 0432 then tried it and got this result:
sort -un filename
315
381
382
0432
433
I had to use sort WITHOUT the u switch followed by uniq to include both 0432 and 432:
sort -n filename | uniq
315
381
382
0432
432
433
