I found the ‘copy styles from template’ command in MS Word AS Reference. Couldn’t find any examples online, so figured it out, and am posting one here.
.
-- define template
property documentTemplate : "~/Documents/TemplateExample.dotx"
tell application "Microsoft Word"
activate
tell active document
-- import styles from template
copy styles from template template documentTemplate
-- select range of text
set titleRng to ¬
create range start (start of content of text object of paragraph 1) ¬
end (end of content of text object of paragraph 1)
-- apply imported style to text range
set (style of titleRng) to "Title"
end tell
end tell
