Extracted FORMS keep order

Hello.

I am using AWS textract and specifically the FORMS functionality to extract just that. It works really good. But the issue I have is that when returning the extracted FORMS, they do not keep their natural order as they come from the document. Is there any way to keep the natural order in the returned objected? Or can I map back to the document order using the coordinates? This is how I use the extraction currently:

def ocr(document):

job_id = start_job(client, BUCKET, document)
is_job_complete(client, job_id)
response = get_job_results(client, job_id) #This is the full object of the OCR
field_list = []
doc = Document(response)
start = 0
for page in doc.pages:
    lst = []
    for field in page.form.fields:
        lst.append("Key: {} Value: {}".format(field.key, field.value))
    field_list.append(lst)
    start = start + 1
text_list = []#Also extract the raw text
for i in range(0,len(response)):
    for item in response[i]["Blocks"]:
        if item["BlockType"] == "LINE":
            text_list.append(item["Text"])
text = " ".join(text_list)
return(field_list, text)

To put it in a real scenario, Example document contains the following FORMS:

A: 123

B: 432

C: 000

D: 126

But the above function returns:

B: 432

A: 123

D: 126

C: 000

Hence not keeping the natural order of working from the top, then left to right, down to the bottom of the document. Is there any setting I can alter earlier or something I can change about my current function to return, the original/natural order?
