Seems easy to do. 
What it looks like to me is:
-
Go to a font generator page and make the letters you need with a glow finish to their outlines.
-
Make sure the inner colors of the letters is the same as the background you’re using. (Solid color)
-
Upload every letter.
-
Apply every letter to the background you choose and set them in the order of the word you’re trying to spell.
-
Copy all positions of each respective letter to a blank notepad. (My method)
-
Scatter the letters to the positions you want them to start in and copy their respective codes to the script.
-
Set opacity for all to 1.
Or set to 0 at start of movement and give them opacity of 1 over a period of time not exceeding the time it takes them to reach their resting positions. -
Collect the codes copied to the notepad and place them after and add the same time to each using “&” as the command beginning and set the last one with “@”.
Eg: - start from opacity 1
&overlay A shifts to #.# in 4
&overlay B shifts to #.# in 4
'@'overlay C shifts to #.# in 4
Eg: -start from opacity 0
&overlay A opacity 1 in 1
&overlay B opacity 1 in 1
&overlay C opacity 1 in 1
&overlay A shifts to #.# in 4
&overlay B shifts to #.# in 4
@'overlay C shifts to #.# in 4
- For blinking effect. This it where having the same color letters and background comes into play.
For every other letter make it’s opacity 0.5 then 1 while the ones that were 1 to 0.5
Eg: -lowercase letters =0.5 and uppercase =1

Add a pause for 0.2 between each interval.
Eg:
&overlay A opacity 1
&overlay B opacity 0
&overlay C opacity 1
'@'pause for 0.2
&overlay A opacity 0
&overlay B opacity 1
&overlay C opacity 0
@'pause for 0.2
&overlay A opacity 1
&overlay B opacity 0
&overlay C opacity 1
@'pause for 0.2
&overlay A opacity 0
&overlay B opacity 1
&overlay C opacity 0
If the timing is too fast or slow, adjust the pause timer.
Hope you understood all of that gibberish above
