Hmm... the indentation seems a bit awry.

                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()

Here's my code for reference. Check the indentation level and the comments:

Code:
# Subroutines
def get_text_data(txt_filename):
    dict_pos = {}
    first_line = True
    for text_root, text_dirs, text_files in os.walk(text_directory):
        for text_file in text_files:
            if text_file == txt_filename:
                # A matching text file was found
                fh = open(os.path.join(text_root, text_file))
                for line in fh:
                    # Skip the header; read the data into the dictionary
                    if first_line:                 # One level inside "for line" loop
                        first_line = False         # One level inside "for line" loop, one level inside "if first_line" branch
                        continue                   # One level inside "for line" loop, one level inside "if first_line" branch
                    line = line.rstrip('\n')       # One level inside "for line" loop
                    x = line.split('\t')           # One level inside "for line" loop
                    dict_pos[x[0]] = x[3]          # One level inside "for line" loop
    return dict_pos                                # One level inside "def"; this is at subroutine level

In your code, the value of "first_line" is True the first time it enters the subroutine and subsequently the first line of "tab_reader".
You then set it to False and then everything else is done inside that "if" branch.
From the second line of "tab_reader" onwards, the control will never go inside the "if" branch because it was set to False in the first line.

Also check the level of "wb.save()" in your code. It should be at the same level as "while cell.value".
