Hi Nick,
I think you could to this using the Find/Replace function, with
something like this:

Find:  (=952.*\$o[^\[]*)(\[[^\[\]]*\])(.*)
Replace:  $1$3

Not sure how familiar you are with the RegExes, so here's a breakdown
of the Find RegEx:
(=952.*\$o          Look for 952 fields that have a subfield o
[^\[]*)                 Followed by any number of characters that is
NOT an opening square bracket
(\[                     Followed by an opening square bracket
[^\[\]]*               Followed by any number of characters that are
NOT either an opening or closing square bracket
\])                     Followed by a closing square bracket
(.*)                    Followed by any number of characters

The 3rd through 5th lines above capture the first square-bracketed
content, and is eliminated in the Replace because it is the "$2"
parenthetical section of the Find RegEx.  (hope that makes sense)

and there may be a simplified version but this seemed to work for me.
cheers,
heidi
