Reference post #8. This is clearly not a Shell script (despite the name of the file). It is some sort of binary file apparently containing executable code.
We don't know what sort of computer course you are doing or what sort of computer you have. I wonder if the tutor is expecting you to disassemble the program first. Bit of a surprise that the "file" command described it as "data" when it appears to be a program, and that "strings" found no program library information.
Have you been working with debugging tools?
Have you covered encryption? (Just wondering if it is encrypted somehow).
If you are on a basic Shell course, it could be that you have been given the wrong file!

SORT(1) General Commands Manual SORT(1)
NAME
sort - sort a file of ASCII lines
SYNOPSIS
sort [-bcdfimnru] [-tc] [-o name] [+pos1] [-pos2] file ...
OPTIONS
-b Skip leading blanks when making comparisons
-c Check to see if a file is sorted
-d Dictionary order: ignore punctuation
-f Fold upper case onto lower case
-i Ignore nonASCII characters
-m Merge presorted files
-n Numeric sort order
-o Next argument is output file
-r Reverse the sort order
-t Following character is field separator
-u Unique mode (delete duplicate lines)
EXAMPLES
sort -nr file # Sort keys numerically, reversed
sort +2 -4 file # Sort using fields 2 and 3 as key
sort +2 -t: -o out # Field separator is :
sort +.3 -.6 # Characters 3 through 5 form the key
DESCRIPTION
Sort sorts one or more files. If no files are specified, stdin is sorted. Output is written on standard output, unless -o is specified.
The options +pos1 -pos2 use only fields pos1 up to but not including pos2 as the sort key, where a field is a string of characters delim-
ited by spaces and tabs, unless a different field delimiter is specified with -t. Both pos1 and pos2 have the form m.n where m tells the
number of fields and n tells the number of characters. Either m or n may be omitted.
