See Standard BED format
http://genome.ucsc.edu/FAQ/FAQformat#format1

  -bedPlus=N - File is bed N+ format

-bedPlus=3 means that only the first 3 columns
are treated as a standard BED file.  Any columns
after 3 are just carried along passively.

Since the format of this data is not a BED 6,
you either need to try to use -bedPlus=3
because only the first 3 columns match
the bed standard, or else re-arranage
the columns into a standard BED 6
so that the strand and name information at least
could be used.  If you need to carry along a
second identifier, the user could make it
into a bed 6 plus with dummy score column of 0.
