Linux command sort issues

Question

I am attempting to sort a .txt file that is full of data. I attempt to sort the file by the first word of aa line in a manner that a dictionary would see it. (I tried the sort -d) The issue that I encounter is this-

Input file

---

100 Eminem:Detroit_Vs._Everybody.txt  
100 Fabolous:She_Wildin'.txt  
100 Fetty_Wap:Trap_Queen.txt  
100 Kanye_West:All_Day.txt  
10 ASAP_Rocky:Lord_Pretty_Flacko_Jodye_2.txt  
10 Bon_Iver:Heavenly_Father.txt  
10% Ed_Sheeran:Take_It_Back.txt  
10 Florida_Georgia_Line:Dirt.txt  
10 Jay_Electronica:Road_To_Perdition.txt

command: sort -d < a.txt

Output

100 Eminem:Detroit_Vs._Everybody.txt  
100 Fabolous:She_Wildin'.txt  
100 Fetty_Wap:Trap_Queen.txt  
100 Kanye_West:All_Day.txt  
10 ASAP_Rocky:Lord_Pretty_Flacko_Jodye_2.txt  
10 Bon_Iver:Heavenly_Father.txt  
10% Ed_Sheeran:Take_It_Back.txt  
10 Florida_Georgia_Line:Dirt.txt  
10 Jay_Electronica:Road_To_Perdition.txt

No change occurs at all. I'm working on a piece of code that uses this data and the way that the 10% comes in between the 10 truly messes up the application.

I would like to see

In other parts of the file, I have similar issues not just with numbers, but with letters and words also. So how do I do this?
