Don't know, but...

Assuming there isn't somethig weird about the column name, It's possible
that the OLEDB provider/ODBC driver that Word uses to get the data has got
mixed up about the type of data in the column, but a quick experiements here
suggests that's unlikely. A few questions:
a. what format does Excel think the cells have (General?). Does it display
any little warning triangles in the corners of the cells?
b. How is the .csv formatted? e.g. is it actually comma-delimited, or is
another character used? Are the values quoted, e.g. using "". Do the numbers
have "thousands separators," e.g. like "123,456.78". If so, what are they,
and what character is used for the decimal point (i.e. are they like
123,456.78, 123.456,78 or what? - and what do your system settings expect?
c. as possible workarounds...
 - try using the .csv directly as a data source
 - open the .csv in Word, save as .doc, and use that
 - change the connection method to the Excel sheet and/or .csv (Word
Tools|Options|General|"Confirm conversions at open, then reconnect tot he
source and select the method in the additional dialog box)
