1) When you tried my code with a bit of manipulation, did you ensure that it reads the file "scores.txt" and not "S12.txt" for the Excel file "S12.xlsx" ?
Yes. its only one file 'scores.txt' that is being used as a reference to get the scores into all excel sheets.

2) If you print dict_pos right before it is returned from the function "get_text_data", what do you see?
It does not return anything

I have pasted the code I used below

Code:

import os
from openpyxl import load_workbook
from datetime import datetime
import csv
  
# Variables
sheet_directory = r'/home/test'
text_directory = r'/home/test'
  
# Subroutines
def get_text_data(txt_filename):
    dict_pos = {}
    first_line = True
    with open('scores.txt') as txt_filename:
        tab_reader = csv.reader(txt_filename, delimiter='\t')
        for line in tab_reader:
            if first_line:
                first_line = False
                continue
                line = line.rstrip('\n')
                x = line.split('\t')
                dict_pos[x[0]] = x[3]
                #print dict_pos
                return dict_pos


def process_xl_sheets():
    for sheet_root, sheet_dirs, sheet_files in os.walk(sheet_directory):
        for sheet_file in sheet_files:
            if sheet_file.endswith('.xlsx'):
                dpos = get_text_data(sheet_file.replace('.xlsx', '.txt'))
                sheet_xl_file = os.path.join(sheet_root, sheet_file)
                wb = load_workbook(sheet_xl_file, data_only=True)
                ws = wb.get_sheet_by_name('raw_data')
                pos_col_no = 'F'
                score_col_no = 'V'
                row_no = 4
                cell = ws[pos_col_no + str(row_no)]
                while cell.value:
                    if str(cell.value) in dpos:
                        ws[score_col_no + str(row_no)] = dpos[str(cell.value)]
                    else:
                        ws[score_col_no + str(row_no)] = 'Unknown_' + datetime.now().strftime("%B") + datetime.now().strftime("%Y")
                        row_no += 1
                        cell = ws[pos_col_no + str(row_no)]
                        wb.save(sheet_xl_file)

                # Main section
process_xl_sheets()
